It is intended for newcomers and experienced administrators alike. This section provides a basic introduction to directory services and, in particular, the directory services provided by slapd(8).

1.1. What is a directory service?

-

A directory is specialized database optimized for reading, browsing and searching. Directories tend to contain descriptive, attribute-based information and support sophisticated filtering capabilities. Directories generally do not support complicated transaction or roll-back schemes found in database management systems designed for handling high-volume complex updates. Directory updates are typically simple all-or-nothing changes, if they are allowed at all. Directories are tuned to give quick-response to high-volume lookup or search operations. They may have the ability to replicate information widely in order to increase availability and reliability, while reducing response time. When directory information is replicated, temporary inconsistencies between the replicas may be okay, as long as they get in sync eventually.

-

There are many different ways to provide a directory service. Different methods allow different kinds of information to be stored in the directory, place different requirements on how that information can be referenced, queried and updated, how it is protected from unauthorized access, etc. Some directory services are local, providing service to a restricted context (e.g., the finger service on a single machine). Other services are global, providing service to a much broader context (e.g., the entire Internet). Global services are usually distributed, meaning that the data they contain is spread across many machines, all of which cooperate to provide the directory service. Typically a global service defines a uniform namespace which gives the same view of the data no matter where you are in relation to the data itself. The Internet Domain Name System is an example of a globally distributed directory service.

1.2. What is LDAP?

-

slapd's model for directory service is based on a global directory model called LDAP. LDAP stands for Lightweight Directory Access Protocol. LDAP is a directory access protocol that runs over TCP/IP. The nitty-gritty details of LDAP are defined in RFC2251 "The Lightweight Directory Access Protocol (v3)." This section gives an overview of LDAP from a user's perspective.

-

What kind of information can be stored in the directory? The LDAP information model is based on entries. An entry is a collection of attributes that has a globally-unique Distinguished Name (DN). The DN is used to refer to the entry unambiguously. Each of the entry's attributes has a type and one or more values. The types are typically mnemonic strings, like "cn" for common name, or "mail" for email address. The syntax of values depend on the attribute type is. For example, cn attribute might be the value Babs Jensen. A mail attribute might contain the value "babs@example.com". A jpegPhoto attribute would contain a photograph in the JPEG (binary) format.

-

How is the information arranged? In LDAP, directory entries are arranged in a hierarchical tree-like structure. Traditionally, this structure reflected the geographic and/or organizational boundaries. Entries representing countries appeared at the top of the tree. Below them are entries representing states and national organizations. Below them might be entries representing organizational units, people, printers, documents, or just about anything else you can think of. Figure 1.1 shows an example LDAP directory tree using traditional naming.

LDAP stands for Lightweight Directory Access Protocol. As the name suggests, it is a lightweight protocol for accessing directory services, specifically X.500-based directory services. LDAP runs over TCP/IP or other connection oriented transfer services. The nitty-gritty details of LDAP are defined in RFC2251 "The Lightweight Directory Access Protocol (v3)" and other documents comprising the technical specification RFC3377. This section gives an overview of LDAP from a user's perspective.

The tree may also be arranged based upon Internet domain names. This naming approach is becoming increasing popular as it allows for directory services to be locating using the Domain Name System. Figure 1.2 shows an example LDAP directory tree using domain-based naming.

Figure 1.2: LDAP directory tree (Internet naming)

In addition, LDAP allows you to control which attributes are required and allowed in an entry through the use of a special attribute called objectClass. The values of the objectClass attribute determine the schema rules the entry must obey.

-

How is the information referenced? An entry is referenced by its distinguished name, which is constructed by taking the name of the entry itself (called the Relative Distinguished Name or RDN) and concatenating the names of its ancestor entries. For example, the entry for Barbara Jensen in the Internet naming example above has an RDN of uid=babs and a DN of uid=babs,ou=People,dc=example,dc=com". The full DN format is described in RFC2253, "Lightweight Directory Access Protocol (v3): UTF-8 String Representation of Distinguished Names."

-

How is the information accessed? LDAP defines operations for interrogating and updating the directory. Operations are provided for adding and deleting an entry from the directory, changing an existing entry, and changing the name of an entry. Most of the time, though, LDAP is used to search for information in the directory. The LDAP search operation allows some portion of the directory to be searched for entries that match some criteria specified by a search filter. Information can be requested from each entry that matches the criteria.

Information can be requested from each entry that matches the criteria.

For example, you might want to search the entire directory subtree at and below dc=example,dc=com for people with the name Barbara Jensen, retrieving the email address of each entry found. LDAP lets you do this easily. Or you might want to search the entries directly below the st=California,c=US entry for organizations with the string Acme in their name, and that have a fax number. LDAP lets you do this too. The next section describes in more detail what you can do with LDAP and how it might be useful to you.

-

How is the information protected from unauthorized access? Some directory services provide no protection, allowing anyone to see the information. LDAP provides a mechanisms for a client to authenticate, or prove its identity to a directory server, paving the way for rich access control to protect the information the server contains. LDAP also supports privacy and integrity security services.

1.3. How does LDAP work?

-

LDAP directory service is based on a client-server model. One or more LDAP servers contain the data making up the LDAP directory tree. An LDAP client connects to an LDAP server and asks it a question. The server responds with the answer and/or with a pointer to where the client can get additional information (typically, another LDAP server). No matter which LDAP server a client connects to, it sees the same view of the directory; a name presented to one LDAP server references the same entry it would at another LDAP server. This is an important feature of a global directory service, like LDAP.

-

1.4. What is slapd and what can it do?

-

slapd is an LDAP directory server that runs on many different platforms. You can use it to provide a directory service of your very own. Your directory can contain pretty much anything you want to put in it. You can connect it to the global LDAP directory service, or run a service all by yourself. Some of slapd's more interesting features and capabilities include:

-

LDAPv2 and LDAPv3: slapd supports both version 2 and 3 of the Lightweight Directory Access Protocol. slapd provides support for the latest features while maintaining interoperability with existing clients. slapd supports both IPv4 and IPv6.

-

Simple Authentication and Security Layer: slapd supports strong authentication services through the use of SASL. slapd's SASL implementation utilizes Cyrus SASL software which supports a number of mechanisms including DIGEST-MD5, EXTERNAL, and GSSAPI.

+

LDAP directory service is based on a client-server model. One or more LDAP servers contain the data making up the directory information tree (DIT). The client connects to servers and asks it a question. The server responds with an answer and/or with a pointer to where the client can get additional information (typically, another LDAP server). No matter which LDAP server a client connects to, it sees the same view of the directory; a name presented to one LDAP server references the same entry it would at another LDAP server. This is an important feature of a global directory service, like LDAP.

+

1.4. What about X.500?

+

Technically, LDAP is a directory access protocol to an X.500 directory service, the OSI directory service. Initially, LDAP clients accessed gateways to the X.500 directory service. This gateway ran LDAP between the client and gateway and X.500's Directory Access Protocol (DAP) between the gateway and the X.500 server. DAP is a heavyweight protocol that operates over a full OSI protocol stack and requires a significant amount of computing resources. LDAP is designed to operate over TCP/IP and provides most of the functionality of DAP at a much lower cost.

+

While LDAP is still used to access X.500 directory service via gateways, LDAP is now more commonly directly implemented in X.500 servers.

+

The stand-alone LDAP daemon, or slapd(8), can be viewed as a lightweight X.500 directory server. That is, it does not implement the X.500's DAP. As a lightweight directory server, slapd(8) implements only a subset of the X.500 models.

+

If you are already running a X.500 DAP service and you want to continue to do so, you can probably stop reading this guide. This guide is all about running LDAP via slapd(8), without running X.500 DAP. If you are not running X.500 DAP, want to stop running X.500 DAP, or have no immediate plans to run X.500 DAP, read on.

+

It is possible to replicate data from an LDAP directory server to a X.500 DAP DSA. This requires an LDAP/DAP gateway. OpenLDAP does not provide such a gateway, but our replication daemon can be used to replicate to such a gateway. See the Replication with slurpd chapter of this document for information regarding replication.

+

1.5. What is the difference between LDAPv2 and LDAPv3?

+

LDAPv3 was developed in the late 1990's to replace LDAPv2. LDAPv3 adds the following features to LDAP:

+ +

LDAPv2 is considered historical. As deploying both LDAPv2 and LDAPv3 simultaneously can be quite problematic, LDAPv2 should be avoided. LDAPv2 is disabled by default.

+

1.6. What is slapd and what can it do?

+

slapd(8) is an LDAP directory server that runs on many different platforms. You can use it to provide a directory service of your very own. Your directory can contain pretty much anything you want to put in it. You can connect it to the global LDAP directory service, or run a service all by yourself. Some of slapd's more interesting features and capabilities include:

+

LDAPv3: slapd implements version 3 of Lightweight Directory Access Protocol. slapd supports LDAP over both IPv4 and IPv6.

+

Simple Authentication and Security Layer: slapd supports strong authentication services through the use of SASL. slapd's SASL implementation utilizes Cyrus SASL software which supports a number of mechanisms including DIGEST-MD5, EXTERNAL, and GSSAPI.

Transport Layer Security: slapd provides privacy and integrity protections through the use of TLS (or SSL). slapd's TLS implementation utilizes OpenSSL software.

-

Access control: slapd provides a rich and powerful access control facility, allowing you to control access to the information in your database(s). You can control access to entries based on LDAP authorization information, IP address, domain name and other criteria. slapd supports both static and dynamic access control information.

+

Topology control: slapd allows one to restrict access to the server based upon network topology. This feature utilizes TCP wrappers.

+

Access control: slapd provides a rich and powerful access control facility, allowing you to control access to the information in your database(s). You can control access to entries based on LDAP authorization information, IP address, domain name and other criteria. slapd supports both static and dynamic access control information.

Internationalization: slapd supports Unicode and language tags.

-

Choice of databases: slapd comes with a variety of different backend databases you can choose from. They include LDBM, a high-performance disk-based embedded database; SHELL, a database interface to arbitrary shell scripts; and PASSWD, a simple password file database. LDBM utilizes either BerkeleyDB or GDBM.

-

Multiple database instances: slapd can be configured to serve multiple databases at the same time. This means that a single slapd server can respond to requests for many logically different portions of the LDAP tree, using the same or different backend databases.

-

Generic modules API: If you require even more customization, slapd lets you write your own modules easily. slapd consists of two distinct parts: a front end that handles protocol communication with LDAP clients; and modules which handle specific tasks such as database operations. Because these two pieces communicate via a well-defined C API, you can write your own customized modules which extend slapd in numerous ways. Also, a number of programmable database modules are provided. These allow you to expose external data sources to slapd using popular programming languages (Perl, Shell, SQL, and TCL).

-

Threads: slapd is threaded for high performance. A single multi-threaded slapd process handles all incoming requests, reducing the amount of system overhead required.

+

Choice of database backends: slapd comes with a variety of different database backends you can choose from. They include BDB, a high-performance transactional database backend; LDBM, a lightweight DBM based backend; SHELL, a backend interface to arbitrary shell scripts; and PASSWD, a simple backend interface to the passwd(5) file. BDB utilizes Sleepycat Berkeley DB. LDBM utilizes either Berkeley DB or GDBM.

+

Threads: slapd is threaded for high performance. A single multi-threaded slapd process handles all incoming requests using a pool of threads. This reduces the amount of system overhead required while providing high performance.

Replication: slapd can be configured to maintain replica copies of its database. This single-master/multiple-slave replication scheme is vital in high-volume environments where a single slapd just doesn't provide the necessary availability or reliability. slapd also includes experimental support for multi-master replication.

Configuration: slapd is highly configurable through a single configuration file which allows you to change just about everything you'd ever want to change. Configuration options have reasonable defaults, making your job much easier.

-

slapd also has its limitations, of course. The main LDBM database backend does not handle range queries or negation queries very well. These features and more will be coming in a future release.

LDAP is designed to operate over TCP/IP and provides most of the functionality of DAP at a much lower cost.

-

This use of LDAP makes it easy to access the X.500 directory, but still requires a full X.500 service to make data available to the many LDAP clients being developed. As with full X.500 DAP clients, a full X.500 DAP server is no small piece of software to operate.

-

The stand-alone LDAP daemon, or slapd(8), is meant to remove much of the burden from the server side just as LDAP itself removed much of the burden from clients. If you are already running a X.500 DAP service and you want to continue to do so, you can probably stop reading this guide, which is all about running LDAP via slapd, without running X.500 DAP. If you are not running X.500 DAP, want to stop running X.500 DAP, or have no immediate plans to run X.500 DAP, read on.

-

It is possible to replicate data from an LDAP directory server to a X.500 DAP DSA. This requires an LDAP/DAP gateway. OpenLDAP does not provide such a gateway, but our replication daemon can be used to replicate to such a gateway. See the Replication with slurpd chapter of this document for information regarding replication.

-

1.6. What is slurpd and what can it do?

-

slurpd(8) is a daemon that helps slapd provide replicated service. It is responsible for distributing changes made to the master slapd database out to the various slapd replicas. It frees slapd from having to worry that some replicas might be down or unreachable when a change comes through; slurpd handles retrying failed requests automatically. slapd and slurpd communicate through a simple text file that is used to log changes.

+

slapd also has its limitations, of course. The main BDB backend does not handle range queries or negation queries very well.

5. The slapd Configuration File

Once the software has been built and installed, you are ready to configure slapd(8) for use at your site. The slapd runtime configuration is primarily accomplished through the slapd.conf(5) file, normally installed in the /usr/local/etc/openldap directory.

An alternate configuration file can be specified via a command-line option to slapd(8) or slurpd(8). This chapter describes the general format of the config file, followed by a detailed description of commonly used config file directives.

5.1. Configuration File Format

-

The slapd.conf(5) file consists of three types of configuration information: global, backend specific, and database specific. Global information is specified first, followed by information associated with a particular backend type, which is then followed by information associated with a particular database instance. Global directives can be overridden in a backend and/or database directives, backend directives can be overridden by database directives.

A configuration directive may take arguments. If so, they are separated by white space. If an argument contains white space, the argument should be enclosed in double quotes "like this". If an argument contains a double quote or a backslash character `\', the character should be preceded by a backslash character `\'.

The distribution contains an example configuration file that will be installed in the /usr/local/etc/openldap directory. A number of files containing schema definitions (attribute types and object classes) are also provided in the /usr/local/etc/openldap/schema directory.

This directive specifies a password for the DN given above that will always work, regardless of whether an entry with the given DN exists or has a password. This directive is deprecated in favor of SASL based authentication.

+

This directive can be used to specifies a password for the DN for the rootdn (when the rootdn is set to a DN within the database).

Example:

         rootpw secret
 
+

It is also permissible to provide hash of the password in RFC 2307 form. slappasswd(8) may be used to generate the password hash.

+

Example:

The hash was generated using the command slappasswd -s secret.

5.2.3.7. suffix <dn suffix>

This directive specifies the DN suffix of queries that will be passed to this backend database. Multiple suffix lines can be given, and at least one is required for each database definition.

5.3. Access Control

Access to slapd entries and attributes is controlled by the access configuration file directive. The general form of an access line is:

Not all of these access control options are described here; for more details see the slapd.access(5) man page.

5.3.1. What to control access to

-

The <what> part of an access specification determines the entries and attributes to which the access control applies. Entries can be selected in two ways: by a regular expression matching the entry's distinguished name:

+

The <what> part of an access specification determines the entries and attributes to which the access control applies. Entries are commonly selected in two ways: by DN and by filter. The following qualifiers select entries by DN:

-        dn=<regular expression>
+        by *
+        by dn[.<basic-style>]=<regex>
+        by dn.<scope-style>=<DN>
 
-


-Note: The DN pattern specified should be "normalized" to the RFC2253 restricted DN form. In particular, there should be no extra spaces and commas should be used to separate components. An example normalized DN is "cn=Babs Jensen,dc=example,dc=com". An example of a non-normalized DN is "cn=Babs Jensen; dc=example; dc=com". -

-

Or, entries may be selected by a filter matching some attribute(s) in the entry:

+

The first form is used to select all entries. The second form may be used to select entries by matching a regular expression against the target entry's normalized DN. (The second form is not discussed further in this document.) The third form is used to select entries which are within the requested scope of DN. The <DN> is a string representation of the Distinguished Name, as described in RFC2253.

+

The scope can be either base, one, subtree, or children. Where base matches only the entry with provided DN, one matches the entries whose parent is the provided DN, subtree matches all entries in the subtree whose root is the provided DN, and children matches all entries under the DN (but not the entry named by the DN).

+

For example, if the directory contained entries named:

-        filter=<ldap filter>
+        0: o=suffix
+        1: cn=Manager,o=suffix
+        2: ou=people,o=suffix
+        3: uid=kdz,ou=people,o=suffix
+        4: cn=addresses,uid=kdz,ou=people,o=suffix
+        5: uid=hyc,ou=people,o=suffix
+
+

Then:

+ +

Entries may also be selected using a filter:

+
+        by filter=<ldap filter>
+
+

where <ldap filter> is a string representation of an LDAP search filter, as described in RFC2254. For example:

+
+        by filter=(objectClass=person)
+
+

Note that entries by be select by both DN and filter by include both qualifiers in the <what> clause.

+
+        by dn.one="ou=people,o=suffix" filter=(objectClass=person)
 
-

where <ldap filter> is a string representation of an LDAP search filter, as described in RFC2254.

Attributes within an entry are selected by including a comma-separated list of attribute names in the <what> selector:

         attrs=<attribute list>
 
-

Access to the entry itself must be granted or denied using the special attribute name "entry". Note that giving access to an attribute is not enough; access to the entry itself through the entry attribute is also required. The complete examples at the end of this section should help clear things up.

+

There are two special psuedo attributes entry and children. To read (and hence return) an target entry, the subject must have read access to the target's entry attribute. To add or delete an entry, the subject must have write access to the entry's entry attribute AND must have write access to the entry's parent's children attribute. To rename an entry, the subject must have write access to entry's entry attribute AND have write access to both the old parent's and new parent's children attributes. The complete examples at the end of this section should help clear things up.

Lastly, there is a special entry selector "*" that is used to select any entry. It is used when no other <what> selector has been provided. It's equivalent to "dn=.*"

5.3.2. Who to grant access to

The <who> part identifies the entity or entities being granted access. Note that access is granted to "entities" not "entries." The following table summarizes entity specifiers:

The DN specifier takes a regular expression which is used to match against the "normalized" DN of the current entity.

By "normalized", we mean that all extra spaces have been removed from the entity's DN and commas are used to separate RDN components.

Other control factors are also supported. For example, a <what> can be restricted by a regular expression matching the client's domain name:

Each level implies all lower levels of access. So, for example, granting someone write access to an entry also grants them read, search, compare, and auth access. However, one may use the privileges specifier to grant specific permissions.

5.3.4. Access Control Evaluation

-

When evaluating whether some requester should be given access to an entry and/or attribute, slapd compares the entry and/or attribute to the <what> selectors given in the configuration file. Access directives local to the current database are examined first, followed by global access directives. Within this priority, access directives are examined in the order in which they appear in the config file. Slapd stops with the first <what> selector that matches the entry and/or attribute. The corresponding access directive is the one slapd will use to evaluate access.

When evaluating whether some requester should be given access to an entry and/or attribute, slapd compares the entry and/or attribute to the <what> selectors given in the configuration file. For each entry, access controls provided in the database which holds the entry (or the first database if not held in any database) apply first, followed by the global access directives. Within this priority, access directives are examined in the order in which they appear in the config file. Slapd stops with the first <what> selector that matches the entry and/or attribute. The corresponding access directive is the one slapd will use to evaluate access.

Next, slapd compares the entity requesting access to the <who> selectors within the access directive selected above in the order in which they appear. It stops with the first <who> selector that matches the requester. This determines the access the entity requesting access has to the entry and/or attribute.

Finally, slapd compares the access granted in the selected <access> clause to the access requested by the client. If it allows greater or equal access, access is granted. Otherwise, access is denied.

The order of evaluation of access directives makes their placement in the configuration file important. If one access directive is more specific than another in terms of the entries it selects, it should appear first in the config file. Similarly, if one <who> selector is more specific than another it should come first in the access directive. The access control examples given below should help make this clear.

+

This directive allows users to modify their own entries if security protections have of strength 128 or better have been established, allows simple authentication and read access when 64 or better security protections have been established.

The following example shows the use of a regular expression to select the entries by DN in two access directives where ordering is significant.

-        access to dn=".*,dc=example,dc=com"
+        access to dn.children="dc=example,dc=com"
                 by * search
-        access to dn=".*,dc=com"
+        access to dn.children="dc=com"
                 by * read
 
-

Read access is granted to entries under the dc=com subtree, except for those entries under the dc=example,dc=com subtree, to which search access is granted. No access is granted to dc=com as neither access directive matches this DN. If the order of these access directives was reversed, the trailing directive would never be reached, since all dc=example,dc=com entries are also dc=com entries.

-

Also note that if no access to directive matches or no by <who> clause, access is denied. That is, every access to directive ends with an implicit by * none clause and every access list ends with an implicit access to * by * none directive. Only if no access controls are specified is the defaultaccess granted.

    8.2.1. Object Identifiers

    Each schema element is identified by a globally unique Object Identifier (OID). OIDs are also used to identify other objects. They are commonly found in protocols described by ASN.1. In particular, they are heavily used by the Simple Network Management Protocol (SNMP). As OIDs are hierarchical, your organization can obtain one OID and branch it as needed. For example, if your organization were assigned OID 1.1, you could branch the tree as follows:

    +

    For private experiments, OIDs under 1.1 may be used. The OID 1.1 arc is regarded as dead name space.

    8.2.2. Name Prefix

    In addition to assigning a unique object identifier to each schema element, you should provide a least one textual name for each element. The name should be both descriptive and not likely to clash with names of other schema elements. In particular, any name you choose should not clash with present or future Standard Track names.

    -

    To reduce (but not eliminate) the potential for name clashes, the convention is to prefix names of non-Standard Track with a few letters to localize the changes to your organization. The smaller the organization, the longer your prefix should be.

    -

    In the examples below, we have choosen a short prefix 'my' (to save space). Such a short prefix would only be suitable for a very large, global organization. For a small, local organization, we recommend something like 'deFirm' (German company) or 'comExample' (elements associated with organization associated with example.com).

It is customary to create a file to contain definitions of your custom schema items.

    +

    9. Security Considerations

    +

    OpenLDAP Software is designed to run in a wide variety of computing environments from tightly-controlled closed networks to the global Internet. Hence, OpenLDAP Software provides many different security mechanisms. This chapter describes these mechanisms and discusses security considerations for using OpenLDAP Software.

    +

    9.1. Network Security

    +

    9.1.1. Selective Listening

    +

    By default, slapd(8) will listen on both the IPv4 and IPv6 "any" addresses. It is often desirable to have slapd listen on select address/port pairs. For example, listening only on the IPv4 address 127.0.0.1 will disallow remote access to the directory server. E.g.:

    +
    +        slapd -h ldap://127.0.0.1
    +
    +

    While the server can be configured to listen on a particular interface address, this doesn't necessarily restrict access to the server to only those networks accessible via that interface. To selective restrict remote access, it is recommend that an IP Firewall be used to restrict access.

    +

    See Command-line Options and slapd(8) for more information.

    +

    9.1.2. IP Firewall

    +

    IP firewall capabilities of the server system can be used to restrict access based upon the client's IP address and/or network interface used to communicate with the client.

    +

    Generally, slapd(8) listens on port 389/tcp for LDAP over TCP (e.g. ldap://) and port 636/tcp for LDAP over SSL (e.g. ldaps://). Note that LDAP over TCP sessions can be protected by TLS through the use of StartTLS. StartTLS is the Standard Track mechanism for protecting LDAP sessions with TLS.

    +

    As specifics of how to configure IP firewall are dependent on the particular kind of IP firewall used, no examples are provided here. See the document associated with your IP firewall.

    +

    9.1.3. TCP Wrappers

    +

    OpenLDAP supports TCP Wrappers. TCP Wrappers provide a rule-based access control system for controlling TCP/IP access to the server. For example, the host_options(5) rule:

    +
    +        slapd: 10.0.0.0/255.0.0.0 127.0.0.1 : ALLOW
    +        slapd: ALL : DENY
    +
    +

    allows only incoming connections from the private network 10.0.0.0 and localhost (127.0.0.1) to access the directory service. Note that IP addresses are used as slapd(8) is not normally configured to perform reverse lookups.

    +

    It is noted that TCP wrappers require the connection to be accepted. As significant processing is required just to deny a connection, it is generally advised that IP firewall protection be used instead of TCP wrappers.

    +

    See hosts_access(5) for more information on TCP wrapper rules.

    +

    9.2. Integrity and Confidentiality Protection

    +

    Transport Layer Security (TLS) can be used to provide integrity and confidentiality protection. OpenLDAP supports both StartTLS and ldaps://. See the Using TLS chapter for more information.

    +

    A number of Simple Authentication and Security Layer (SASL) mechanisms, such as DIGEST-MD5 and GSSAPI, also provide integrity and confidentiality protection. See the Using SASL chapter for more information.

    +

    9.2.1. Security Strength Factors

    +

    The server uses Security Strength Factors (SSF) to indicate the relative strength of protection. A SSF of zero (0) indicates no protections are in place. A SSF of one (1) indicates integrity protection are in place. A SSF greater than one (>1) roughly correlates to the effective encryption key length. For example, DES is 56, 3DES is 112, and AES 128, 192, or 256.

    +

    A number of administrative controls rely on SSFs associated with TLS and SASL protection in place on an LDAP session.

    +

    security controls disallow operations when appropriate protections are not in place. For example:

    +
    +        security ssf=1 update_ssf=112
    +
    +

    requires integrity protection for all operations and encryption protection, 3DES equivalent, for update operations (e.g. add, delete, modify, etc.). See slapd.conf(5) for details.

    +

    For fine-grained control, SSFs may be used in access controls. See Access Control section of the The slapd Configuration File for more information.

    +

    9.3. Authentication Methods

    +

    9.3.1. "simple" method

    +

    The LDAP "simple" method has three modes of operation:

    +
      +
    • anonymous, +
    • unauthenticated, and +
    • user/password authenticated.
    +

    Anonymous access is obtained by providing no name and no password to the "simple" bind operation. Unauthenticated access is obtained by providing a name but no password. Authenticated access is obtain by providing a valid name and password.

    +

    An anonymous bind results in an anonymous authorization. Anonymous bind mechanism is enabled by default, but can be disabled by specifying "disallow bind_anon" in slapd.conf(5).

    +

    An unauthenticated bind results in an anonymous authorization. Unauthenticated bind mechanism is disabled by default, but can be enabled by specifying "allow bind_anon_cred" in slapd.conf(5). As a number of LDAP applications mistakenly generate unauthenticated bind request when authenticated access was intended (that is, they do not ensure a password was provided), this mechanism should generally not be enabled.

    +

    A successful user/password authenticated bind results in a user authorization identity, the provided name, being associated with the session. User/password authenticated bind is enabled by default. However, as this mechanism offers no evesdropping protection (e.g., the password is set in the clear), it is recommended that it be used only in tightly controlled systems or when the LDAP session is protected by other means (e.g., TLS, IPSEC). Where the administrator relies on TLS to protect the password, it is recommended that unprotected authentication be disabled. This is done by setting "disallow bind_simple_unprotected" in slapd.conf(5). The security directive's simple_bind option provides fine grain control over the level of confidential protection to require for simple user/password authentication.

    +

    The user/password authenticated bind mechanism can be completely disabled by setting "disallow bind_simple".

    +


    +Note: An unsuccessful bind always results in the session having an anonymous authorization state. +

    +

    9.3.2. SASL method

    +

    The LDAP SASL method allows use of any SASL authentication mechanism. The Using SASL discusses use of SASL.

    +

    +
    +

    10. Using SASL

    +

    OpenLDAP clients and servers are capable of authenticating via the Simple Authentication and Security Layer (SASL) framework, which is detailed in RFC2222. This chapter describes how to make use of SASL in OpenLDAP.

    +

    There are several industry standard authentication mechanisms that can be used with SASL, including Kerberos V4, GSSAPI, and DIGEST-MD. The standard client tools provided with OpenLDAP, such as ldapsearch(1) and ldapmodify(1), will by default attempt to authenticate the user to the slapd(8) server using SASL. Basic authentication service can be set up by the LDAP administrator with a few steps, allowing users to be authenticated to the slapd server as their LDAP entry. With a few extra steps, some users and services can be allowed to exploit SASL's proxy authorization feature, allowing them to authenticate themselves and then switch their identity to that of another user or service.

    +

    This chapter assumes you have read Cyrus SASL for System Administrators, provided with the Cyrus SASL package (in doc/sysadmin.html) and have a working Cyrus SASL installation. You should use the Cyrus SASL sample_client and sample_server to test your SASL installation before attempting to make use of it in OpenLDAP.

    +

    Note that in the following text the term user is used to describe a person or application entity who is connecting to the LDAP server via an LDAP client, such as ldapsearch(1). That is, the term user not only applies to both an individual using an LDAP client, but to an application entity which issues LDAP client operations without direct user control. For example, an e-mail server which uses LDAP operations to access information held in an LDAP server is an application entity.

    +

    10.1. SASL Security Considerations

    +

    SASL offers many different authentication mechanisms. This section briefly outlines security considerations.

    +

    Some mechanisms, such as PLAIN and LOGIN, offer no greater security over LDAP "simple" authentication. Like "simple" authentication, such mechanisms should not be used unless you have adequate security protections in place. It is recommended that these mechanisms be used only in conjunction with Transport Layer Security (TLS). Use of PLAIN and LOGIN are not discussed further in this document.

    +

    The DIGEST-MD5 mechanism is the mandatory-to-implement authentication mechanism for LDAPv3. Though DIGEST-MD5 is not a strong authentication mechanism in comparison with trusted third party authentication systems (such as Kerberos or public key systems), yet it does offer significant protections against a number of attacks. Unlike the CRAM-MD5 mechanism, it prevents chosen plaintext attacks. DIGEST-MD5 is favored over the weaker and even more dangerous use of plaintext password mechanisms. The CRAM-MD5 mechanism is deprecated in favor of DIGEST-MD5. Use of DIGEST-MD5 is discussed below.

    +

    The KERBEROS_V4 mechanism utilizes Kerberos IV to provide secure authentication services. There is also a GSSAPI based mechanism which is generally used in conjunction with Kerberos V. Kerberos is viewed as a secure, distributed authentication system suitable for both small and large enterprises. Use of KERBEROS_V4 and GSSAPI are discussed below.

    +

    The EXTERNAL mechanism utilizes authentication services provided by lower level network services such as TLS (TLS). When used in conjunction with TLS X.509-based public key technology, EXTERNAL offers strong authentication. Use of EXTERNAL is discussed in the Using TLS chapter.

    +

    There are other strong authentication mechanisms to choose from, including OTP (one time passwords) and SRP (secure remote passwords). These mechanisms are not discussed in this document.

    +

    10.2. SASL Authentication

    +

    Getting basic SASL authentication running involves a few steps. The first step configures your slapd server environment so that it can communicate with client programs using the security system in place at your site. This usually involves setting up a service key, a public key, or other form of secret. The second step concerns mapping authentication identities to LDAP DN's, which depends on how entries are laid out in your directory. An explanation of the first step will be given in the next section using Kerberos V4 as an example mechanism. The steps necessary for your site's authentication mechanism will be similar, but a guide to every mechanism available under SASL is beyond the scope of this chapter. The second step is described in the section Mapping Authentication identities to LDAP entries.

    +

    10.2.1. KERBEROS_V4

    +

    This section describes the use of the SASL KERBEROS_V4 mechanism with OpenLDAP. It will be assumed that you are familiar with the workings of the Kerberos IV security system, and that your site has Kerberos IV deployed. Your users should be familiar with authentication policy, how to receive credentials in a Kerberos ticket cache, and how to refresh expired credentials.

    +

    Client programs will need to be able to obtain a session key for use when connecting to your LDAP server. This allows the LDAP server to know the identity of the user, and allows the client to know it is connecting to a legitimate server. If encryption layers are to be used, the session key can also be used to help negotiate that option.

    +

    The slapd server runs the service called "ldap", and the server will require a srvtab file with a service key. SASL aware client programs will be obtaining an "ldap" service ticket with the user's ticket granting ticket (TGT), with the instance of the ticket matching the hostname of the OpenLDAP server. For example, if your realm is named EXAMPLE.COM and the slapd server is running on the host named directory.example.com, the /etc/srvtab file on the server will have a service key

    +
    +        ldap.directory@EXAMPLE.COM
    +
    +

    When an LDAP client is authenticating a user to the directory using the KERBEROS_IV mechanism, it will request a session key for that same principal, either from the ticket cache or by obtaining a new one from the Kerberos server. This will require the TGT to be available and valid in the cache as well. If it is not present or has expired, SASL will print out the message

    +
    +        ldap_sasl_interactive_bind_s: Local error
    +
    +

    When the service ticket is obtained, it will be passed to the LDAP server as proof of the user's identity. The server will extract the identity and realm out of the service ticket using SASL library calls, and convert them into an authentication request DN of the form

    +
    +        uid=<username>,cn=<realm>,cn=<mechanism>,cn=auth
    +
    +

    So in our above example, if the user's name were "adamson", the authentication request DN would be:

    +
    +        uid=adamsom,cn=example.com,cn=kerberos_v4,cn=auth
    +
    +

    This authentication request DN by itself could be placed into ACL's and groupOfNames "member" attributes, since it is of legitimate LDAP DN format. The section Mapping Authentication identities to LDAP entries, however, tells how to map that DN into the DN of a person's own LDAP entry.

    +

    Also note that this example, being for Kerberos, shows the <realm> portion of the DN being filled in with the Kerberos realm of the company. Several other authentication mechanisms do not employ the concept of a realm, so the ",cn=<realm>" portion of the authentication request DN would not appear.

    +

    10.2.2. GSSAPI

    +

    This section describes the use of the SASL GSSAPI mechanism and Kerberos V with OpenLDAP. Since Kerberos V is being used, the information is very similar to the previous section. It will be assumed that you have Kerberos V deployed, you are familiar with the operation of the system, and that your users are trained in its use. This section also assumes you have familiarized yourself with the use of the GSSAPI mechanism by reading Configuring GSSAPI and Cyrus SASL (provided with Cyrus SASL in the doc/gssapi file) and successfully experimented with the Cyrus provided sample_server and sample_client applications. General information about Kerberos is available at http://web.mit.edu/kerberos/www/.

    +

    To use the GSSAPI mechanism with slapd(8) one must create a service key with a principal for ldap service within the realm for the host on which the service runs. For example, if you run slapd on directory.example.com and your realm is EXAMPLE.COM, you need to create a service key with the principal:

    +
    +        ldap/directory.example.com@EXAMPLE.COM
    +
    +

    When slapd(8) runs, it must have access to this key. This is generally done by placing the key into a keytab, such as /etc/krb5.keytab.

    +

    To use the GSSAPI mechanism to authenticate to the directory, the user obtains a Ticket Granting Ticket (TGT) prior to running the LDAP client. When using OpenLDAP client tools, the user may mandate use of the GSSAPI mechanism by specifying -Y GSSAPI as a command option.

    +

    For the purposes of authentication and authorization, slapd(8) associates a non-mapped authentication request DN of the form:

    +
    +        uid=<principal>,cn=<realm>,cn=gssapi,cn=auth
    +
    +

    Continuing our example, a user with the Kerberos principal kurt@EXAMPLE.COM would have the associated DN:

    +
    +        uid=kurt,cn=example.com,cn=gssapi,cn=auth
    +
    +

    and the principal ursula@FOREIGN.REALM would have the associated DN:

    +
    +        uid=ursula,cn=foreign.realm,cn=gssapi,cn=auth
    +
    +

    10.2.3. DIGEST-MD5

    +

    This section describes the use of the SASL DIGEST-MD5 mechanism using secrets stored either in the directory itself or in Cyrus SASL's own database. DIGEST-MD5 relies on the client and the server sharing a "secret", usually a password. The server generates a challenge and the client a response proving that it knows the shared secret. This is much more secure than simply sending the secret over the wire.

    +

    Cyrus SASL supports several shared-secret mechanisms. To do this, it needs access to the plaintext password (unlike mechanisms which pass plaintext passwords over the wire, where the server can store a hashed version of the password).

    +

    Secret passwords are normally stored in Cyrus SASL's own sasldb database, but if OpenLDAP has been compiled with Cyrus SASL 2.1 it is possible to store the secrets in the LDAP database itself. With Cyrus SASL 1.5, secrets may only be stored in the sasldb. In either case it is very important to apply file access controls and LDAP access controls to prevent exposure of the passwords.

    +

    The configuration and commands discussed in this section assume the use of Cyrus SASL 2.1. If you are using version 1.5 then certain features will not be available, and the command names will not have the trailing digit "2".

    +

    To use secrets stored in sasldb, simply add users with the saslpasswd2 command:

    +
    +       saslpasswd2 -c <username>
    +
    +

    The passwords for such users must be managed with the saslpasswd2 command.

    +

    To use secrets stored in the LDAP directory, place plaintext passwords in the userPassword attribute. It will be necessary to add an option to slapd.conf to make sure that passwords changed through LDAP are stored in plaintext:

    +
    +       password-hash   {CLEARTEXT}
    +
    +

    Passwords stored in this way can be managed either with ldappasswd or by simply modifying the userPassword attribute.

    +

    Wherever the passwords are stored, a mapping will be needed from SASL authentication IDs to regular DNs. The DIGEST-MD5 mechanism produces authentication IDs of the form:

    +
    +        uid=<username>,cn=<realm>,cn=digest-md5,cn=auth
    +
    +

    NOTE that if the default realm is used, the realm name is omitted from the ID, giving:

    +
    +        uid=<username>,cn=digest-md5,cn=auth
    +
    +

    See Mapping Authentication identities to LDAP entries below for information on mapping such IDs to DNs.

    +

    With suitable mappings in place, users can specify SASL IDs when performing LDAP operations, and the password stored in sasldb or in the directory itself will be used to verify the authentication. For example, the user identified by the directory entry:

    +
    +       dn: cn=Andrew Findlay+uid=u000997,dc=example,dc=com
    +       objectclass: inetOrgPerson
    +       objectclass: person
    +       sn: Findlay
    +       uid: u000997
    +       userPassword: secret
    +
    +

    can issue commands of the form:

    +
    +       ldapsearch -U u000997 -b dc=example,dc=com 'cn=andrew*'
    +
    +

    or can specify the realm explicitly:

    +
    +       ldapsearch -U u000997@myrealm -b dc=example,dc=com 'cn=andrew*'
    +
    +

    If several SASL mechanisms are supported at your site, it may be necessary to specify which one to use, e.g.:

    +
    +       ldapsearch -Y DIGEST-MD5 -U u000997 -b dc=example,dc=com 'cn=andrew*'
    +
    +


    +Note: in each of the above cases, no authorization identity (e.g. -X) was provided. Unless you are attempting SASL Proxy Authorization, no authorization identity should be specified. The server will infer an authorization identity from authentication identity (as described below). +

    +

    10.2.4. Mapping Authentication identities to LDAP entries

    +

    The authentication mechanism in the slapd server will use SASL library calls to obtain the authenticated user's "username", based on whatever underlying authentication mechanism was used. This username is in the namespace of the authentication mechanism, and not in the LDAP namespace. As stated in the sections above, that username is reformatted into an authentication request DN of the form

    +
    +        uid=<username>,cn=<realm>,cn=<mechanism>,cn=auth
    +
    +

    or

    +
    +        uid=<username>,cn=<mechanism>,cn=auth
    +
    +

    depending on whether or not <mechanism> employs the concept of "realms". Note also that the realm part will be omitted if the default realm was used in the authentication.

    +

    It is not intended that you should add LDAP entries of the above form to your LDAP database. Chances are you have an LDAP entry for each of the people that will be authenticating to LDAP, laid out in your directory tree, and the tree does not start at cn=auth. But if your site has a clear mapping between the "username" and an LDAP entry for the person, you will be able to configure your LDAP server to automatically map a authentication request DN to the user's authentication DN.

    +


    +Note: it is not required that the authentication request DN nor the user's authentication DN resulting from the mapping refer to an entry held in the directory. However, additional capabilities become available (see below). +

    +

    The LDAP administrator will need to tell the slapd server how to map an authentication request DN to a user's authentication DN. This is done by adding one or more sasl-regexp directives to the slapd.conf(5) file. This directive takes two arguments:

    +
    +        sasl-regexp   <search pattern>   <replacement pattern>
    +
    +

    The authentication request DN is compared to the search pattern using the regular expression functions regcomp() and regexec(), and if it matches, it is rewritten as the replacement pattern. If there are multiple sasl-regexp directives, only the first whose search pattern matches the authentication identity is used. The string that is output from the replacement pattern should be the authentication DN of the user, in a legitimate LDAP DN format. It can also be an LDAP URL, which is discussed below.

    +

    The search pattern can contain any of the regular expression characters listed in regexec(3C). The main characters of note are dot ".", asterisk "*", and the open and close parenthesis "(" and ")". Essentially, the dot matches any character, the asterisk allows zero or more repeats of the immediately preceding character or pattern, and terms in parenthesis are remembered for the replacement pattern.

    +

    The replacement pattern will produce the final authentication DN of the user. Anything from the authentication request DN that matched a string in parenthesis in the search pattern is stored in the variable "$1". That variable "$1" can appear in the replacement pattern, and will be replaced by the string from the authentication request DN. If there were multiple sets of parentheses in the search pattern, the variables $2, $3, etc are used.

    +

    For example, suppose the user's authentication identity is written as the DN string

    +
    +        uid=adamson,cn=example.com,cn=kerberos_v4,cn=auth
    +
    +

    and the user's actual LDAP entry is

    +
    +        uid=adamson,ou=person,dc=example,dc=com
    +
    +

    The sasl-regexp directive in slapd.conf(5) could be written

    +
    +        sasl-regexp
    +          uid=(.*),cn=example.com,cn=kerberos_v4,cn=auth
    +          uid=$1,ou=person,dc=example,dc=com
    +
    +

    An even more lenient rule could be written as

    +
    +        sasl-regexp
    +          uid=(.*),cn=.*,cn=auth
    +          uid=$1,ou=person,dc=example,dc=com
    +
    +

    Be careful about setting the search pattern too leniently, however, since it may mistakenly allow people to become authenticated as a DN to which they should not have access. It is better to write several strict directives than one lenient directive which has security holes. If there is only one authentication mechanism in place at your site, and zero or one realms in use, you might be able to map between authentication identities and LDAP DN's with a single sasl-regexp directive.

    +

    Don't forget to allow for the case where the realm is omitted as well as the case with an explicitly specified realm. This may well require a separate sasl-regexp directive for each case, with the explicit-realm entry being listed first.

    +

    Some sites may have people's DN's spread to multiple areas of the LDAP tree, such as if there were an ou=accounting tree and an ou=engineering tree, with people interspersed between them. Or there may not be enough information in the authentication identity to isolate the DN, such as if the above person's LDAP entry looked like

    +
    +        dn: cn=mark adamson,ou=person,dc=example,dc=com
    +        objectclass: Person
    +        cn: mark adamson
    +        uid: adamson
    +
    +

    In this case, the information in the authentication identity can only be used to search for the user's DN, not derive it directly. For both of these situations, and others, the replacement pattern in the sasl-regexp directives will need to produce an LDAP URL, described in the next section.

    +

    10.2.5. Performing searches for a person's DN

    +

    When there is not enough information in the authentication identity to derive a person's authentication DN directly, the sasl-regexp directives in the slapd.conf(5) file will need to produce an LDAP URL. This URL will then be used to perform an internal search of the LDAP database to find the person's authentication DN.

    +

    An LDAP URL, similar to other URL's, is of the form

    +
    +        ldap://<host>/<base>?<attrs>?<scope>?<filter>
    +
    +

    This contains all of the elements necessary to perform an LDAP search: the name of the server <host>, the LDAP DN search base <base>, the LDAP attributes to retrieve <attrs>, the search scope <scope> which is one of the three options "base", "one", or "sub", and lastly an LDAP search filter <filter>. Since the search is for an LDAP DN within the current server, the <host> portion should be empty. The <attrs> field is also ignored since only the DN is of concern. These two elements are left in the format of the URL to maintain the clarity of what information goes where in the string.

    +

    Suppose that the person in the example from above did in fact have an authentication username of "adamson" and that information was kept in the attribute "uid" in their LDAP entry. The sasl-regexp directive might be written as

    +
    +        sasl-regexp
    +          uid=(.*),cn=example.com,cn=kerberos_v4,cn=auth
    +          ldap:///ou=person,dc=example,dc=com??sub?(uid=$1)
    +
    +

    This will initiate an internal search of the LDAP database inside the slapd server. If the search returns exactly one entry, it is accepted as being the DN of the user. If there are more than one entries returned, or if there are zero entries returned, the authentication fails and the user's connection is left bound as the authentication request DN.

    +

    Note that if the search scope <scope> in the URL is "base", then the only LDAP entry that will be returned is the searchbase DN <base>, so the actual search of the database is skipped. This is equivalent to setting the replacement pattern in the directive to a DN directly, as in the section above.

    +

    The attributes that are used in the search filter <filter> in the URL should be indexed to allow faster searching. If they are not, the authentication step alone can take uncomfortably long periods, and users may assume the server is down.

    +

    A more complex site might have several realms in use, each mapping to a different sub-tree in the directory. These can be handled with statements of the form:

    +
    +        # Match Engineering realm

    +

    Note that the explicitly-named realms are handled first, to avoid the realm name becoming part of the UID. Note also the limitation of matches to those entries with (objectClass=person) to avoid matching other entries that happen to refer to the UID.

    See slapd.conf(5) for more detailed information.

    +

    10.3. SASL Proxy Authorization

    +

    The SASL offers a feature known as proxy authorization, which allows an authenticated user to request that they act on the behalf of another user. This step occurs after the user has obtained an authentication DN, and involves sending an authorization identity to the server. The server will then make a decision on whether or not to allow the authorization to occur. If it is allowed, the user's LDAP connection is switched to have a binding DN derived from the authorization identity, and the LDAP session proceeds with the access of the new authorization DN.

    +

    The decision to allow an authorization to proceed depends on the rules and policies of the site where LDAP is running, and thus cannot be made by SASL alone. The SASL library leaves it up to the server to make the decision. The LDAP administrator sets the guidelines of who can authorize to what identity by adding information into the LDAP database entries. By default, the authorization features are disabled, and must be explicitly configured by the LDAP administrator before use.

    +

    10.3.1. Uses of Proxy Authorization

    +

    This sort of service is useful when one entity needs to act on the behalf of many other users. For example, users may be directed to a web page to make changes to their personal information in their LDAP entry. The users authenticate to the web server to establish their identity, but the web server CGI cannot authenticate to the LDAP server as that user to make changes for them. Instead, the web server authenticates itself to the LDAP server as a service identity, say,

    +
    +        cn=WebUpdate,dc=example,dc=com
    +
    +

    and then it will SASL authorize to the DN of the user. Once so authorized, the CGI makes changes to the LDAP entry of the user, and as far as the slapd server can tell for its ACLs, it is the user themself on the other end of the connection. The user could have connected to the LDAP server directly and authenticated as themself, but that would require the user to have more knowledge of LDAP clients, knowledge which the web page provides in an easier format.

    +

    Proxy authorization can also be used to limit access to an account that has greater access to the database. Such an account, perhaps even the root DN specified in slapd.conf(5), can have a strict list of people who can authorize to that DN. Changes to the LDAP database could then be only allowed by that DN, and in order to become that DN, users must first authenticate as one of the persons on the list. This allows for better auditing of who made changes to the LDAP database. If people were allowed to authenticate directly to the priviliged account, possibly through the rootpw slapd.conf(5) directive or through a userPassword attribute, then auditing becomes more difficult.

    +

    Note that after a successful proxy authorization, the original authentication DN of the LDAP connection is overwritten by the new DN from the authorization request. If a service program is able to authenticate itself as its own authentication DN and then authorize to other DN's, and it is planning on switching to several different identities during one LDAP session, it will need to authenticate itself each time before authorizing to another DN (or use a different proxy authorization mechanism). The slapd server does not keep record of the service program's ability to switch to other DN's. On authentication mechanisms like Kerberos this will not require multiple connections being made to the Kerberos server, since the user's TGT and "ldap" session key are valid for multiple uses for the several hours of the ticket lifetime.

    +

    10.3.2. SASL Authorization Identities

    +

    The SASL authorization identity is sent to the LDAP server via the -X switch for ldapsearch(1) and other tools, or in the *authzid parameter to the lutil_sasl_defaults() call. The identity can be in one of two forms, either

    +
    +        u:<username>
    +
    +

    or

    +
    +        dn:<dn>
    +
    +

    In the first form, the <username> is from the same namespace as the authentication identities above. It is the user's username as it is refered to by the underlying authentication mechanism. Authorization identities of this form are converted into a DN format by the same function that the authentication process used, producing an authorization request DN of the form

    +
    +        uid=<username>,cn=<realm>,cn=<mechanism>,cn=auth
    +
    +

    That authorization request DN is then run through the same sasl-regexp process to convert it into a legitimate authorization DN from the database. If it cannot be converted due to a failed search from an LDAP URL, the authorization request fails with "inappropriate access". Otherwise, the DN string is now a legitimate authorization DN ready to undergo approval.

    +

    If the authorization identity was provided in the second form, with a "dn:" prefix, the string after the prefix is already in authorization DN form, ready to undergo approval.

    +

    10.3.3. Proxy Authorization Rules

    +

    Once slapd has the authorization DN, the actual approval process begins. There are two attributes that the LDAP administrator can put into LDAP entries to allow authorization:

    +
    +        saslAuthzTo
    +        saslAuthzFrom
    +
    +

    Both can be multivalued. The saslAuthzTo attribute is a source rule, and it is placed into the entry associated with the authentication DN to tell what authorization DNs the authenticated DN is allowed to assume. The second attribute is a destination rule, and it is placed into the entry associated with the requested authorization DN to tell which authenticated DNs may assume it.

    +

    The choice of which authorization policy attribute to use is up to the administrator. Source rules are checked first in the person's authentication DN entry, and if none of the saslAuthzTo rules specify the authorization is permitted, the saslAuthzFrom rules in the authorization DN entry are then checked. If neither case specifies that the request be honored, the request is denied. Since the default behaviour is to deny authorization requests, rules only specify that a request be allowed; there are no negative rules telling what authorizations to deny.

    +

    The value(s) in the two attributes are of the same form as the output of the replacement pattern of a sasl-regexp directive: either a DN or an LDAP URL. For example, if a saslAuthzTo value is a DN, that DN is one the authenticated user can authorize to. On the other hand, if the saslAuthzTo value is an LDAP URL, the URL is used as an internal search of the LDAP database, and the authenticated user can become ANY DN returned by the search. If an LDAP entry looked like:

    +
    +        dn: cn=WebUpdate,dc=example,dc=com
    +        saslAuthzTo: ldap:///dc=example,dc=com??sub?(objectclass=Person)
    +
    +

    then any user who authenticated as cn=WebUpdate,dc=example,dc=com could authorize to any other LDAP entry under the search base "dc=example,dc=com" which has an objectClass of "Person".

    +

    10.3.3.1. Notes on Proxy Authorization Rules

    +

    An LDAP URL in a saslAuthzTo or saslAuthzFrom attribute will return a set of DNs. Each DN returned will be checked. Searches which return a large set can cause the authorization process to take an uncomfortably long time. Also, searches should be performed on attributes that have been indexed by slapd.

    +

    To help produce more sweeping rules for saslAuthzFrom and saslAuthzTo, the values of these attributes are allowed to be DNs with regular expression characters in them. This means a source rule like

    +
    +        saslAuthzTo: uid=.*,dc=example,dc=com
    +
    +

    would allow that authenticated user to authorize to any DN that matches the regular expression pattern given. This regular expression comparison can be evaluated much faster than an LDAP search for (uid=*).

    +

    Also note that the values in an authorization rule must be one of the two forms: an LDAP URL or a DN (with or without regular expression characters). Anything that does not begin with "ldap://" is taken as a DN. It is not permissable to enter another authorization identity of the form "u:<username>" as an authorization rule.

    +

    10.3.3.2. Policy Configuration

    +

    The decision of which type of rules to use, saslAuthzFrom or saslAuthzTo, will depend on the site's situation. For example, if the set of people who may become a given identity can easily be written as a search filter, then a single destination rule could be written. If the set of people is not easily defined by a search filter, and the set of people is small, it may be better to write a source rule in the entries of each of those people who should be allowed to perform the proxy authorization.

    +

    By default, processing of proxy authorization rules is disabled. The sasl-authz-policy directive must be set in the slapd.conf(5) file to enable authorization. This directive can be set to none for no rules (the default), from for source rules, to for destination rules, or both for both source and destination rules.

    +

    Destination rules are extremely powerful. If ordinary users have access to write the saslAuthzTo attribute in their own entries, then they can write rules that would allow them to authorize as anyone else. As such, when using destination rules, the saslAuthzTo attribute should be protected with an ACL that only allows privileged users to set its values.

    +

    +
    +

    11. Using TLS

    +

    OpenLDAP clients and servers are capable of using the Transport Layer Security (TLS) framework to provide integrity and confidentiality protections and to support LDAP authentication using the SASL EXTERNAL mechanism.

    +

    11.1. TLS Certificates

    +

    TLS uses X.509 certificates to carry client and server identities. All servers are required to have valid certificates, whereas client certificates are optional. Clients must have a valid certificate in order to authenticate via SASL EXTERNAL. For more information on creating and managing certificates, see the OpenSSL documentation.

    +

    11.1.1. Server Certificates

    +

    The DN of a server certificate must use the CN attribute to name the server, and the CN must carry the server's fully qualified domain name. Additional alias names and wildcards may be present in the subjectAltName certificate extension. More details on server certificate names are in RFC2830.

    +

    11.1.2. Client Certificates

    +

    The DN of a client certificate can be used directly as an authentication DN. Since X.509 is a part of the X.500 standard and LDAP is also based on X.500, both use the same DN formats and generally the DN in a user's X.509 certificate should be identical to the DN of their LDAP entry. However, sometimes the DNs may not be exactly the same, and so the mapping facility described in Mapping Authentication identities to LDAP entries can be applied to these DNs as well.

    +

    11.2. TLS Configuration

    +

    After obtaining the required certificates, a number of options must be configured on both the client and the server to enable TLS and make use of the certificates. At a minimum, the clients must be configured with the filename containing all of the Certificate Authority (CA) certificates it will trust. The server must be configured with the CA certificates and also its own server certificate and private key.

    +

    Typically a single CA will have issued the server certificate and all of the trusted client certificates, so the server only needs to trust that one signing CA. However, a client may wish to connect to a variety of secure servers managed by different organizations, with server certificates generated by many different CAs. As such, a client is likely to need a list of many different trusted CAs in its configuration.

    +

    11.2.1. Server Configuration

    +

    The configuration directives for slapd belong in the global directives section of slapd.conf(5).

    +

    11.2.1.1. TLSCACertificateFile <filename>

    +

    This directive specifies the PEM-format file containing certificates for the CA's that slapd will trust. The certificate for the CA that signed the server certificate must be included among these certificates. If the signing CA was not a top-level (root) CA, certificates for the entire sequence of CA's from the signing CA to the top-level CA should be present. Multiple certificates are simply appended to the file; the order is not significant.

    +

    11.2.1.2. TLSCACertificatePath <path>

    +

    This directive specifies the path of a directory that contains individual CA certificates in separate files. In addition, this directory must be specially managed using the OpenSSL c_rehash utility. When using this feature, the OpenSSL library will attempt to locate certificate files based on a hash of their name and serial number. The c_rehash utility is used to generate symbolic links with the hashed names that point to the actual certificate files. As such, this option can only be used with a filesystem that actually supports symbolic links. In general, it is simpler to use the TLSCACertificateFile directive instead.

    +

    11.2.1.3. TLSCertificateFile <filename>

    +

    This directive specifies the file that contains the slapd server certificate. Certificates are generally public information and require no special protection.

    +

    11.2.1.4. TLSCertificateKeyFile <filename>

    +

    This directive specifies the file that contains the private key that matches the certificate stored in the TLSCertificateFile file. Private keys themselves are sensitive data and are usually password encrypted for protection. However, the current implementation doesn't support encrypted keys so the key must not be encrypted and the file itself must be protected carefully.

    +

    11.2.1.5. TLSCipherSuite <cipher-suite-spec>

    +

    This directive configures what ciphers will be accepted and the preference order. <cipher-suite-spec> should be a cipher specification for OpenSSL. You can use the command

    +
    +        openssl ciphers -v ALL
    +
    +

    to obtain a verbose list of available cipher specifications. Besides the individual cipher names, the specifiers HIGH, MEDIUM, LOW, EXPORT, and EXPORT40 may be helpful, along with TLSv1, SSLv3, and SSLv2.

    +

    11.2.1.6. TLSRandFile <filename>

    +

    This directive specifies the file to obtain random bits from when /dev/urandom is not available. If the system provides /dev/urandom then this option is not needed, otherwise a source of random data must be configured. Some systems (e.g. Linux) provide /dev/urandom by default, while others (e.g. Solaris) require the installation of a patch to provide it, and others may not support it at all. In the latter case, EGD or PRNGD should be installed, and this directive should specify the name of the EGD/PRNGD socket. The environment variable RANDFILE can also be used to specify the filename. Also, in the absence of these options, the .rnd file in the slapd user's home directory may be used if it exists. To use the .rnd file, just create the file and copy a few hundred bytes of arbitrary data into the file. The file is only used to provide a seed for the pseudo-random number generator, and it doesn't need very much data to work.

    +

    11.2.1.7. TLSVerifyClient { never | allow | try | demand }

    +

    This directive specifies what checks to perform on client certificates in an incoming TLS session, if any. This option is set to never by default, in which case the server never asks the client for a certificate. With a setting of allow the server will ask for a client certificate; if none is provided the session proceeds normally. If a certificate is provided but the server is unable to verify it, the certificate is ignored and the session proceeds normally, as if no certificate had been provided. With a setting of try the certificate is requested, and if none is provided, the session proceeds normally. If a certificate is provided and it cannot be verified, the session is immediately terminated. With a setting of demand the certificate is requested and a valid certificate must be provided, otherwise the session is immediately terminated.

    +


    +Note: The server must request a client certificate in order to use the SASL EXTERNAL authentication mechanism with a TLS session. As such, a non-default TLSVerifyClient setting must be configured before SASL EXTERNAL authentication may be attempted, and the SASL EXTERNAL mechanism will only be offered to the client if a valid client certificate was received. +

    +

    11.2.2. Client Configuration

    +

    Most of the client configuration directives parallel the server directives. The names of the directives are different, and they go into ldap.conf(5) instead of slapd.conf(5), but their functionality is mostly the same. Also, while most of these options may be configured on a system-wide basis, they may all be overridden by individual users in their .ldaprc files.

    +

    11.2.2.1. TLS_CACERT <filename>

    +

    This is equivalent to the server's TLSCACertificateFile option. As noted in the TLS Configuration section, a client typically may need to know about more CAs than a server, but otherwise the same considerations apply.

    +

    11.2.2.2. TLS_CACERTDIR <path>

    +

    This is equivalent to the server's TLSCACertificatePath option. The specified directory must be managed with the OpenSSL c_rehash utility as well.

    +

    11.2.2.3. TLS_CERT <filename>

    +

    This directive specifies the file that contains the client certificate. This is a user-only directive and can only be specified in a user's .ldaprc file.

    +

    11.2.2.4. TLS_KEY <filename>

    +

    This directive specifies the file that contains the private key that matches the certificate stored in the TLS_CERT file. The same constraints mentioned for TLSCertificateKeyFile apply here. This is also a user-only directive.

    +

    11.2.2.5. TLS_RANDFILE <filename>

    +

    This directive is the same as the server's TLSRandFile option.

    +

    11.2.2.6. TLS_REQCERT { never | allow | try | demand }

    +

    This directive is equivalent to the server's TLSVerifyClient option. However, for clients the default value is demand and there generally is no good reason to change this setting.

    +

    11.2.2.7. TLS { never | hard }

    +

    This directive specifies whether client connections should use TLS by default. The default setting is never which specifies that connections will be opened in the clear unless TLS is explicitly specified using an "ldaps://" URL. When set to hard all connections will be established with TLS, as if an "ldaps://" URL was specified. Note that the use of ldaps is a holdover from LDAPv2 and this setting is incompatible with the LDAPv3 StartTLS request. As such, it's best not to use this option.

    +

    +

    12. Constructing a Distributed Directory Service

    For many sites, running one or more slapd(8) that hold an entire subtree of data is sufficient. But often it is desirable to have one slapd refer to other directory services for a certain part of the tree (which may or may not be running slapd).

    A referral object has a structural object class of referral and has the same Distinguished Name as the delegated subtree. Generally, the referral object will also provide the auxiliary object class extensibleObject. This allows the entry to contain appropriate Relative Distinguished Name values. This is best demonstrated by example.

    If the server a.example.net holds dc=example,dc=net and wished to delegate the subtree ou=subtree,dc=example,dc=net to another server b.example.net, the following named referral object would be added to a.example.net:

    +

    13. Replication with slurpd

    In certain configurations, a single slapd(8) instance may be insufficient to handle the number of clients requiring directory service via LDAP. It may become necessary to run more than one slapd instance. At many sites, for instance, there are multiple slapd servers: one master and one or more slaves. DNS can be setup such that a lookup of ldap.example.com returns the IP addresses of these servers, distributing the load among them (or just the slaves). This master/slave arrangement provides a simple and effective way to increase capacity, availability and reliability.

    slurpd(8) provides the capability for a master slapd to propagate changes to slave slapd instances, implementing the master/slave replication scheme described above. slurpd runs on the same host as the master slapd instance.

    13.4. Configuring slurpd and a slave slapd instance

    To bring up a replica slapd instance, you must configure the master and slave slapd instances for replication, then shut down the master slapd so you can copy the database. Finally, you bring up the master slapd instance, the slave slapd instance, and the slurpd instance. These steps are detailed in the following sections. You can set up as many slave slapd instances as you wish.

    13.4.1. Set up the master slapd

    The following section assumes you have a properly working slapd(8) instance. To configure your working slapd(8) server as a replication master, you need to make the following changes to your slapd.conf(5).

    1. Add a replica directive for each replica. The binddn= parameter should match the updatedn option in the corresponding slave slapd configuration file, and should name an entry with write permission to the slave database (e.g., an entry listed as rootdn, or allowed access via access directives in the slave slapd configuration file).
    2. Add a replogfile directive, which tells slapd where to log changes. This file will be read by slurpd.

    13.4.3. Shut down the master server

    In order to ensure that the slave starts with an exact copy of the master's data, you must shut down the master slapd. Do this by sending the master slapd process an interrupt signal with kill -INT <pid>, where <pid> is the process-id of the master slapd process.

    If you like, you may restart the master slapd in read-only mode while you are replicating the database. During this time, the master slapd will return an "unwilling to perform" error to clients that attempt to modify data.

    10.4.4. Copy the master slapd's database to the slave

    -

    Copy the master's database(s) to the slave. For an LDBM-based database, you must copy all database files located in the database directory specified in slapd.conf(5). Database files will have a different suffix depending on the underlying database package used. The current possibilities are

The reject file is located in the same directory as the per-replica replication logfile, and has the same name, but with the string ".rej" appended. For example, for a replica running on host slave.example.com, port 389, the reject file, if it exists, will be named

    13.5.2. One-shot mode and reject files

    It is possible to use slurpd to process a rejection log with its "one-shot mode." In normal operation, slurpd watches for more replication records to be appended to the replication log file. In one-shot mode, by contrast, slurpd processes a single log file and exits. Slurpd ignores ERROR lines at the beginning of replication log entries, so it's not necessary to edit them out before feeding it the rejection log.

    To use one-shot mode, specify the name of the rejection log on the command line as the argument to the -r flag, and specify one-shot mode with the -o flag. For example, to process the rejection log file /usr/local/var/openldap/replog.slave.example.com:389 and exit, use the command
