============================================================

When moving a student (user) to another school all his classes (groups) are removed before he is moved to the new ou and assigned to new classes. In some cases the S4-Connector doesn't find the DN of the user and fails to removed it from the old groups but resyncs the obsolete group membership back to ucs. Now the old classes (groups) contains the orphaned old student (user).

Comment 1 Arvid Requate univentionstaff 2018-03-21 22:03:50 CET 
From the logs this looks very similar to Bug 46682:

univention/s4connector/s4/__init__.py", line 1812, in group_members_sync_from_ucs

But I cannot reproduce *that* bug until now. In UCS@school we have a default of connector/s4/mapping/group/syncmode=write, but user object get synchronized in both ways, and that *may* cause group sync to get sync'ed back. The connector-s4.log file shows "sync to ucs" for the affected user objects.

But I cannot reproduce it. Additionally to the steps of Bug 46682 Comment 1 I've stopped the notifier on the master before performing the steps and started it later again. All modifications replicated successfully.

I think we should first try to fix Bug 46682. I guess that would fix this one too. As Stefan pointed out, the situation of this Ticket #2018020121000154 is more complex because there is an additional AD-Connector involved.
