Description Florian Best 2015-02-02 10:13:46 CET

This error is now handled in UDM so that this cannot happen in future anymore.
But if there are existing broken systems they are still unable to use the UCS@school wizards. We should also handle this in UCS@school directly.

Or provide something to clean up the ldap for dead references.

+++ This bug was initially created as a clone of Bug #35099 +++

We received the following traceback on a UCS@school 3.2R2 UCS 3.2-2 errata121 (Borgfeld).
We had similar tracebacks before due to missing objects/containers in the OU structure.

Traceback:
