Description Sönke Schwardt-Krummrich

+++ This bug was initially created as a clone of Bug #33731 +++

On a DC backup and a DC slave an inconsistency between ldap content and listener cache occurred. After calling univention-replicate-one the listener checked the upstream object against the listener cache and jumped to the next transaction because according to the cache the system was up-to-date:

11.12.13 15:29:05.335  LISTENER    ( ALL     ) : handler: replication considered
11.12.13 15:29:05.335  LISTENER    ( INFO    ) : handler: replication (up-to-date)

The listener should always pass the retrieved object to the replication module - no matter if the listener cache has already seen this object.

The exception for the replication module has already been implemented for errata 3.1-0 but it was ineffective due to a logic flaw.

Advisory: 2013-12-19-univention-directory-listener.yaml

I've added a test case to ucs-test for this issue: 10_ldap/48replication_listener_cache_up_to_date_check

YAML: OK
