+++ This bug was initially created as a clone of Bug #37668 +++

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:
Die Ausführung des Kommandos schoolwizards/computers/query ist fehlgeschlagen:
