Description Sönke Schwardt-Krummrich 2018-11-30 11:00:11 CET

If "username" is missing in the UDM CLI argument list during "users/user create", an ugly traceback is shown instead of an useful error message:

master# udm users/user create --position cn=users,dc=example,dc=com \
            --set lastname=Nachname --set password=univention
