[Samba] changes on DC not replicated, while showrepl reports no issues

[mj]

Hi Louis,

Never noticed there are only five different unknown invocation IDs, they 
just repaet. :-)

We have only three DCs now, but:

We used to have three, of which we (years ago) ditched two, keeping one 
and added two new ones. So totally in our AD ever has known 5 DCs at 
different times.

Same here! No out of syncs there. (it does show "unknown invocation ID" 
in it's output)
