Problem: Join Fails In 92univention-management-console-web-server.inst


Joining a new server fails in 92univention-management-console-web-server.inst.


The to-be-joined server is at least at UCS version 4.4-3e443 while the master server is still at a previous version.
The /var/log/univention/join.log shows this:

W: The config registry variable
'ucs/web/overview/entries/admin/umc/description/de' does not exist
LDAP Error: Undefined attribute type: signLogouts: attribute type undefined


This is a bug. As workaround upgrade your master at least to UCS version 4.4-3e443 and start the join again.

Note: It is strongly recommended to make sure the master is always newer or equal than any other server in the same UCS domain.
