I have a couple of Samba4 AD DCs replicating with Windows Server 2008 DCs. This
has been sort of finicky, but I've managed to get it to work (mostly) for
several weeks. However, I'm now having an issue where one of my Samba4 DCs
will not replicate from any of the other DCs (Windows or Samba) in the domain
(Error is WERR_BAD_NET_RESP). Replication output is below. If anyone has ideas
of what to try, next, to get this going, again, I'd be happy to give it a
shot. Alternatively, if anyone knows of a way to easily remove the data from
the Samba DC and re-replicate it (without having to actually de-join and re-join
the DC and deal GUID changes and such), I'd like to give that a shot, too.
FWIW, running "repadmin /sync /force /full" on one of the Windows DCs
didn't help.
Thanks,
Nick
