Select a particular subtree of the directory information tree (DIT) to search for user entries. The subtree is
specified by a DN, which specifies the base node of the subtree. For example, by setting this option to
ou=Users,ou=corp, dc=corp, dc=example, dc=com, the search for user entries is restricted to the subtree beneath
ou=Users, ou=corp, dc=corp, dc=example, dc=com.
