[Samba] AD error 8418: The replication operation failed because of a schema mismatch between the servers involved (WERR_DS_DRA_SCHEMA_MISMATCH)
Hello,
we are running a 2008 R2 AD (schema 47) with two DCs:
* dc-win (Windows 2008 R2)
* dc-samba (samba 4.5.12, Debian stable)
Since some weeks replication works only from dc-win to dc-samba but not
in the other direction.:(
root at dc-samba:~# samba-tool drs replicate dc-samba dc-win dc=credativ,dc=de
Replicate from dc-win to dc-samba was successful.
root at dc-samba:~# samba-tool drs replicate dc-win dc-samba dc=credativ,dc=de
ERROR(<class 'samba.drs_utils.drsException'>): DsReplicaSync
failed - drsException: DsReplicaSync failed (8418,

File "/usr/lib/python2.7/dist-packages/samba/netcmd/drs.py", line

File "/usr/lib/python2.7/dist-packages/samba/drs_utils.py", line 83,

I found the same problem in the mailinglist but I could find a solving
