Description Sönke Schwardt-Krummrich univentionstaff 2019-02-28 15:50:21 CET
Upon first initialization, the listener module ucsschool-s4-branch-site.py fails to connect to the local LDAP server with the following traceback. Next, all listener modules are initialized but not the module ucsschool-s4-branch-site.py. 
After initialization of the listener, which is logged to join.log, the listener is restarted, notices the uninitialized listener module ucsschool-s4-branch-site.py which is then initialized.

We should try to prevent the long traceback and print a more apropriate single line log message.
