+++ This bug was initially created as a clone of Bug #34763 +++

Ticket#: 2014050721007513

At a customer 5 DC slaves thought they had a valid/established TCP connection to the DC backup port 7389 and were waiting for LDAP search results. But on the DC backup all those TCP connections were unknown and seem to be shut down for some time. Since the slaves do not send any data (waiting for LDAP responses), the will not recognize that the TCP connection is broken and has to be reestablished.


We should activate the TCP keep alive function within listener for notifier/LDAP connections, so the listener is able to detect broken connections.
