UCS 4.0-4 errata 408, UCS@school 4.0 R2 (ucsschool_20160115)

A customer experiences the following traceback on almost every school slave:

I will attach the log with connector/debug/level='4' at Ticket#2016040421000103

I guess we need to check which objectclass cn=microsoft and cn=microsoft have in cases like these. Maybe the con_subtree_delete_objects filter (Bug 33882) just needs to be extended. If that is the case, then Bug 45311 should be considered too.
