(In reply to Florian Best from Bug #34244 comment #9)

As we received that side note we could adapt the error message to also mention that the available/free disk size should be checked and give the hint to free resources (also RAM, ...) to minimize the load.

+++ This bug was initially created as a clone of Bug #34244 +++

We received multiple tracebacks that the LDAP Server can not be contacted.

Instead of a traceback a meaningful message should be shown.
The exception could be catched in the module loading of UMC.

LDAP_ConnectionError: Opening LDAP connection failed: {'desc': "Can't contact LDAP
server"}

Comment 2 Florian Best univentionstaff 2014-11-28 13:20:52 CET 
* On a DC slave now the message "Check the available hard disk space and RAM on the domaincontroller master" occurs.
* Not everybody knows what RAM is. Please use a more common term like memory/etc.

Maybe something like:
Make sure enough disk space and free memory is available [if-non-master] on this system and the domaincontoller master[/if-non-master].
