Problem:
Some shares are not accessable with some clients, but with some others it is possible, accessing e.g. the marktplatz share. The personal user share is always accessable.
Since it is the same user, from the same network to the same Samba server, the question arises, why it works on one computer and not on the others.
Investigation:
samba logs shows
Denied connection from 172.25.136.29

Solution:
These entrys seem to be generated during exam-mode, and were not cleaned up properly.
/usr/share/ucs-school-exam/exam-and-room-cleanup will removed these entries.
