[Fedora-directory-users] FDS - AD: sync deactivated status

Dear all, i have a FDS with synchronization to an AD up and running, everything including password sync is fine, the only attribute that is needed and not synching is whether the user is deactivated or not. I can deactive users seperately in FDS or AD but it does not sync, after alot of research i could not find a solution for that, can someone please point me the way ? Regards Soeren
