Please check if a test case is possible. +++ This bug was initially created as a clone of Bug #34809 +++ 2014051221009038 http://forum.univention.de/viewtopic.php?f=48&t=3198&p=11228 If a license with key-id is added, the key-id is written to UCR uuid/license. If a license without key-id is imported afterwards, the app center complains about the missing key-id, asks the user to request a new one but refuses to import is due to the key-id already set in uuid/license. If a license without a key-id is imported, the UCR variable uuid/license should be unset.
