[Samba] ERROR(<class 'samba.drs_utils.drsException'>): DsReplicaSync failed - drsException: DsReplicaSync failed (-1073610699, 'The operation cannot be performed.')

Hi  All,

since Friday I get a surprising error, when I try to replicate my 
domain-controllers.
This is new! It worked before in any direction without any failures...

When I replicate from dc2 to dc1 this runs also, without any failures:
root at dc1:~# samba-tool drs replicate dc1 dc2 
DC=mydomain,DC=uni-frankfurt,DC=de
Replicate from dc2 to dc1 was successful.

Only when I try to replicate from dc1 to dc2 I get this new failure:
root at dc1:~# samba-tool drs replicate dc2 dc1 
DC=mydomain,DC=uni-frankfurt,DC=de
ERROR(<class 'samba.drs_utils.drsException'>): DsReplicaSync failed - 
drsException: DsReplicaSync failed (-1073610699, 'The operation cannot 
be performed.')
   File "/usr/lib/python2.7/dist-packages/samba/netcmd/drs.py", line 
348, in run
     drs_utils.sendDsReplicaSync(self.drsuapi, self.drsuapi_handle, 
source_dsa_guid, NC, req_options)
   File "/usr/lib/python2.7/dist-packages/samba/drs_utils.py", line 83, 
in sendDsReplicaSync
     raise drsException("DsReplicaSync failed %s" % estr)

Is this a bug?
