This is a follow-up to this question: I added the memberof overlay to an existing OpenLDAP 2.4 server. Now I want to update the existing user objects.

For new group memberships, the memberOf attribute is updated correctly. But I have a bunch of existing groups which aren't updated automatically. I could remove all users from their groups and re-add them to make sure these entries are in sync. Since this is a Univention Corporate Server which does a lot of magic when you modify the LDAP, I don't want to risk breaking my directory.

Is there a way to trick the overlay to update these operational attributes?
