Our school's website has the ability to pull user authentication from a LDAP source. They "support" and LDAP. Unfortunately, to pull group membership you must have a memberOf attribute in each users' record. OS X Lion Server does not store users group membership in their record by default.
I've read about OpenLDAP's memberOf overlay, and I am hoping that will work. But I don't know how to set it up, I've read the comment on How do I configure Reverse Group Membership Maintenance on an openldap server? (memberOf) but I'm not comfortable importing the LDIF until I know better what it does and if I have to import an ldif for each user. Also, I believe Open Directory uses posixGroups not a groupOfNames.
Questions: Is it possible to enable the memberOf attribute in Apple's OS X Open Directory implementation of OpenLDAP? If I enable it will it dynamically update the memberOf attribute when I add users to groups with Workgroup Manager? How do I enable the memberOf attribute?
