+OpenSSH LDAP keystore Patch
+===========================
+
+NOTE: these notes are a transcript of a specific installation
+ they work for me, your specifics may be different!
+ from John Lane March 17th 2005 john@lane.uk.net
+
+This is a patch to OpenSSH 4.0p1 to allow it to obtain users' public keys
+from their LDAP record as an alternative to ~/.ssh/authorized_keys.
+
+(Assuming here that necessary build stuff is in $BUILD)
+
+cd $BUILD/openssh-4.0p1
+patch -Np1 -i $BUILD/openssh-lpk-4.0p1-0.3.patch
+mkdir -p /var/empty &&
+./configure --prefix=/usr --sysconfdir=/etc/ssh \
+ --libexecdir=/usr/sbin --with-md5-passwords --with-pam \
+ --with-libs="-lldap" --with-cppflags="-DWITH_LDAP_PUBKEY"
+Now do.
+make &&
+make install
+
+Add the following config to /etc/ssh/ssh_config
+UseLPK yes
+LpkServers ldap://myhost.mydomain.com
+LpkUserDN ou=People,dc=mydomain,dc=com
+
+We need to tell sshd about the SSL keys during boot, as root's
+environment does not exist at that time. Edit /etc/rc.d/init.d/sshd.
+Change the startup code from this:
+ echo "Starting SSH Server..."
+ loadproc /usr/sbin/sshd
+ ;;
+to this:
+ echo "Starting SSH Server..."
+ LDAPRC="/root/.ldaprc" loadproc /usr/sbin/sshd
+ ;;
+
+Re-start the sshd daemon:
+/etc/rc.d/init.d/sshd restart
+
+Install the additional LDAP schema
+cp $BUILD/openssh-lpk-0.2.schema /etc/openldap/schema/openssh.schema
+
+Now add the openSSH LDAP schema to /etc/openldap/slapd.conf:
+Add the following to the end of the existing block of schema includes
+include /etc/openldap/schema/openssh.schema
+
+Re-start the LDAP server:
+/etc/rc.d/init.d/slapd restart
+
+To add one or more public keys to a user, eg "testuser" :
+ldapsearch -x -W -Z -LLL -b "uid=testuser,ou=People,dc=mydomain,dc=com" -D
+"uid=testuser,ou=People,dc=mydomain,dc=com" > /tmp/testuser
+
+append the following to this /tmp/testuser file
+objectclass: ldapPublicKey
+sshPublicKey: ssh-rsa
+AAAAB3NzaC1yc2EAAAABJQAAAIB3dsrwqXqD7E4zYYrxwdDKBUQxKMioXy9pxFVai64kAPxjU9KS

+7eZE/gVbn2UQkQq7+kdDTS2yXV6VnC52N/kKLG3ciBkBAw== General Purpose RSA Key
+
+Then do a modify:
+ldapmodify -x -D "uid=testuser,ou=People,dc=mydomain,dc=com" -W -f
+/tmp/testuser -Z
+Enter LDAP Password:
+modifying entry "uid=testuser,ou=People,dc=mydomain,dc=com"
+And check the modify is ok:
+ldapsearch -x -W -Z -b "uid=testuser,ou=People,dc=mydomain,dc=com" -D
+"uid=testuser,ou=People,dc=mydomain,dc=com"
+Enter LDAP Password:
+# extended LDIF
+#
+# LDAPv3
+# base <uid=testuser,ou=People,dc=mydomain,dc=com> with scope sub
+# filter: (objectclass=*)
+# requesting: ALL
+#
+
+# testuser, People, mydomain.com
+dn: uid=testuser,ou=People,dc=mydomain,dc=com
+uid: testuser
+cn: testuser
+objectClass: account

+
+Now start a ssh session to user "testuser" from usual ssh client (e.g.

+
+purposes of this patch:
+
+This patch would help to have authentication centralization policy
+using ssh public key authentication.
+This patch could be an alternative to other "secure" authentication system
+working in a similar way (Kerberos, SecurID, etc...), except the fact
+that it's based on OpenSSH and its public key abilities.
+
+>> FYI: <<
+'uid': means unix accounts existing on the current server
+'ServerGroup:' mean server group configured on the current server by the SSH_Filter option in the ldap.conf.
+
+example schema:
+
+
+ server1 (uid: eau,rival,toto) (ServerGroup: unix)
+ ___________ /
+ / \ --- - server3 (uid: eau, titi) (ServerGroup: unix)
+ | LDAP Server | \
+ | eau ,rival | server2 (uid: rival, eau) (ServerGroup: unix)
+ | titi ,toto |
+ | userx,.... | server5 (uid: eau) (ServerGroup: mail)
+ \___________/ \ /
+ ----- - server4 (uid: eau, rival) (no group configured)
+ \
+ etc...
+
+- WHAT WE NEED :
+
+ * configured LDAP server somewhere on the network (i.e. OpenLDAP)
+ * patched sshd (with this patch ;)
+ * LDAP user(/group) entry (look at users.ldif (& groups.ldif)):
+ User entry:
+ - attached to the 'ldapPublicKey' objectclass
+ - attached to the 'posixAccount' objectclass
+ - with a filled 'sshPublicKey' attribute
+ Example:
+ dn: uid=eau,ou=users,dc=cuckoos,dc=net
+ objectclass: top
+ objectclass: person
+ objectclass: organizationalPerson
+ objectclass: posixAccount
+ objectclass: ldapPublicKey
+ description: Eric AUGE Account
+ userPassword: blah
+ cn: Eric AUGE
+ sn: Eric AUGE
+ uid: eau
+ uidNumber: 1034
+ gidNumber: 1
+ homeDirectory: /export/home/eau
+ sshPublicKey: ssh-dss AAAAB3...
+ sshPublicKey: ssh-dss AAAAM5...
+
+ Group entry:
+ - attached to the 'posixGroup' objectclass
+ - with a 'cn' groupname attribute
+ - with multiple 'memberUid' attributes filled with usernames allowed in this group
+ Example:
+ # few members
+ dn: cn=unix,ou=groups,dc=cuckoos,dc=net
+ objectclass: top
+ objectclass: posixGroup
+ description: Unix based servers group
+ cn: unix
+ gidNumber: 1002
+ memberUid: eau
+ memberUid: user1
+ memberUid: user2
+
+
+- HOW IT WORKS :
+
+ * without patch
+ If a user wants to authenticate to log in a server the sshd, will first look for authentication method allowed (RSAauth,kerberos,etc..)
+ and if RSAauth and tickets based auth fails, it will fallback to standard password authentication (if enabled).
+
+ * with the patch
+ If a user want to authenticate to log in a server, the sshd will first look for auth method including LDAP pubkey, if the ldappubkey options is enabled.
+ It will do an ldapsearch to get the public key directly from the LDAP instead of reading it from the server filesystem.
+ (usually in $HOME/.ssh/authorized_keys)
+
+ 2 tokens are added to sshd_config :
+ # here is the new patched ldap related tokens
+ PubkeyAgent /usr/libexec/openssh/ssh-ldap-helper -s %u
+ PubkeyAgentRunAs nobody
+
+ The LDAP configuratin is read from common /etc/ldap.conf configuration file.
+There is also one optional parameter in the LDAP configuration file, SSH_Filter, which is a LDAP filter limiting keys to be searched.
+
+- HOW TO INSERT A USER/KEY INTO AN LDAP ENTRY
+
+ * my way (there is plenty :)
+ - create ldif file (i.e. users.ldif)
+ - cat ~/.ssh/id_dsa.pub OR cat ~/.ssh/id_rsa.pub OR cat ~/.ssh/identity.pub
+ - my way in 4 steps :
+ Example:
+
+ # you add this to the user entry in the LDIF file :
+ [...]
+ objectclass: posixAccount
+ objectclass: ldapPublicKey
+ [...]
+ sshPubliKey: ssh-dss AAAABDh12DDUR2...
+ [...]
+
+ # insert your entry and you're done :)
+ ldapadd -D balblabla -w bleh < file.ldif
+
+ all standard options can be present in the 'sshPublicKey' attribute.
+
+- WHY :
+
+ Simply because, i was looking for a way to centralize all sysadmins authentication, easily, without completely using LDAP
+ as authentication method (like pam_ldap etc..).
+
+ After looking into Kerberos, SecurID, and other centralized secure authentications systems, the use of RSA and LDAP to get
+ public key for authentication allows us to control who has access to which server (the user needs an account and to be in 'strongAuthenticationUser'
+ objectclass within LDAP and part of the group the SSH server is in).
+
+ Passwords update are no longer a nightmare for a server farm (key pair passphrase is stored on each user's box and private key is locally encrypted using his passphrase
+ so each user can change it as much as he wants).
+
+ Blocking a user account can be done directly from the LDAP (if sshd is using RSAAuth + ldap only).
+
+- RULES :
+ Entry in the LDAP server must respect 'posixAccount' and 'ldapPublicKey' which are defined in core.schema.
+ and the additionnal lpk.schema.
+
+ This patch could allow a smooth transition between standard auth (/etc/passwd) and complete LDAP based authentication
+ (pamldap, nss_ldap, etc..).
+
+ This can be an alternative to other (old?/expensive?) authentication methods (Kerberos/SecurID/..).
+
+ Referring to schema at the beginning of this file if user 'eau' is only in group 'unix'
+ 'eau' would ONLY access 'server1', 'server2', 'server3' AND 'server4' BUT NOT 'server5'.
+ If you then modify the LDAP 'mail' group entry to add 'memberUid: eau' THEN user 'eau' would be able
+ to log in 'server5' (i hope you got the idea, my english is bad :).
+
+ Each server's sshd is patched and configured to ask the public key and the group infos in the LDAP
+ server.
+ When you want to allow a new user to have access to the server parc, you just add him an account on
+ your servers, you add his public key into his entry on the LDAP server, it's done.
+
+ Because sshds are looking public keys into the LDAP directly instead of a file ($HOME/.ssh/authorized_keys).
+
+ When the user needs to change his passphrase he can do it directly from his workstation by changing
+ his own key set lock passphrase, and all servers are automatically aware.
+
+ With a CAREFUL LDAP server configuration you could allow a user to add/delete/modify his own entry himself
+ so he can add/modify/delete himself his public key when needed.
+
+<2B> FLAWS :
+ LDAP must be well configured, getting the public key of some user is not a problem, but if anonymous LDAP
+ allow write to users dn, somebody could replace someuser's public key by its own and impersonate some
+ of your users in all your server farm be VERY CAREFUL.
+
+ MITM attack when sshd is requesting the public key, could lead to a compromise of your servers allowing login
+ as the impersonnated user.
+
+ If LDAP server is down then, no fallback on passwd auth.
+
+ the ldap code part has not been well audited yet.

+Multiple 'sshPublicKey' in a user entry are allowed, as well as multiple 'memberUid' attributes in a group entry
+
+- COMPILING:
+ 1. Apply the patch
+ 2. ./configure --with-your-options --with-ldap=/prefix/to/ldap_libs_and_includes
+ 3. make
+ 4. it's done.
+
+- BLA :
+ I hope this could help, and i hope to be clear enough,, or give ideas. questions/comments/improvements are welcome.
