I'm trying to get the Samba4 multi-master replication to work.
I set up the primary domain controller using this howto (under CentOS
I installed bind 9.8.3 and enabled encrypted dns updates.
I set up another VM with the same CentOS version and oriented myself on
to join the second DC into the domain. I edited /etc/resolv.conf and set
the nameserver to the IP of the primary DC (bind dns server).
Basic replication seems to work (not doing the rsync for sysvol yet).
However, when i take the primary DC offline, I can't use any of the .msc
domain admin tools anymore.
I always get an error message, telling me that there is no RPC server
When i run gpmc.msc i can choose the DC i want to work on and I can see
the secondary one, but it will come back with the RPC error.
User authentication does still work and Kerberos tickets are generated
by the 2nd DC.
I can find this in the log:
../source4/dsdb/kcc/kcc_topology.c:1402: failed to find nCName attribute
../source4/dsdb/kcc/kcc_topology.c:3158: failed to color vertices:
../source4/dsdb/kcc/kcc_topology.c:3415: failed to create connections:
Warning: 60 extra bytes in incoming RPC request
../source4/rpc_server/drsuapi/dcesrv_drsuapi.c:74: doing DsBind with
Do i need to configure something extra, so the secondary DC will be able
to act as an RPC server?
