+Some common custom SSSD settings are:
+
+  * `enumerate` \- Set to 'true' to cache all user and group entries from the directory service. Disabling this could add a short delay to users' first login.
+
+  * `ldap_id_mapping` \- Set to 'true' to map LDAP/AD user and group IDs to local UIDs and GIDs on the Linux system. Enabling this can improve compatibility with existing POSIX scripts and applications.
