+ <title>CERTIFICATE MAPPING SECTION</title>
+ <para>
+ To allow authentication with Smartcards and certificates SSSD must
+ be able to map certificates to users. This can be done by adding the
+ full certificate to the LDAP object of the user or to a local
+ override. While using the full certificate is required to use the
+ Smartcard authentication feature of SSH (see
+ <citerefentry>
+ <refentrytitle>sss_ssh_authorizedkeys</refentrytitle>
+ <manvolnum>8</manvolnum>
+ </citerefentry>
+ for details) it might be cumbersome or not even possible to do this
+ for the general case where local services use PAM for
+ authentication.
+ </para>
+ <para>
+ To make the mapping more flexible mapping and matching rules were
+ added to SSSD (see
+ <citerefentry>
+ <refentrytitle>sss-certmap</refentrytitle>
+ <manvolnum>5</manvolnum>
+ </citerefentry>
+ for details).
+ </para>
+ <para>
+ A mapping and matching rule can be added to the SSSD configuration
+ in a section on its own with a name like
+ <quote>[certmap/<replaceable>DOMAIN_NAME</replaceable>/<replaceable>RULE_NAME</replaceable>]</quote>.
+ In this section the following options are allowed:
+ </para>
+ <variablelist>
+ <varlistentry>
+ <term>matchrule (string)</term>

+ <para>
+ Only certificates from the Smartcard which matches this
+ rule will be processed, all others are ignored.
