For example, you could mimic the behavior of LDAP BaseDN by specifying \"uid=#UID,ou=People,dc=cloudera,dc=com\". When the username of \"mike\" comes in, it replaces the #UID and the result is \"uid=mike,ou=People,dc=cloudera,dc=com\". This option should be used when more control over the DN is needed. This parameter is mutually exclusive with LDAP Domain and LDAP BaseDN.",
