samba - Feb 2013 - Smaba 4.0.3 replication: Warning: No NC replicated for Connection!

Hi folks,

I think I've read every thread on this issue and don't seem to be able
to
resolve it. It doesn't appear to be affecting anything, however I'm not
entirely sure what the implications are either way.

What should I do to troubleshoot it? I have BIND9_FLAT updating a BIND
server, all of the records appear correct, regular AD objects are
replicated fine as well.

Any help appreciated. Thanks!
