[Samba] Samba4 - Corrupted group caused stop of replication - "Object class violation"

[Olivier BILHAUT]

Hi Samba List! 

We are using Samba Version 4.1.12 on two master DC.


We've noticed that a corrupted group has been created, we tried to
delete it, and since then, the replication fail between the two DC.


The result of the command : "samba-tool drs showrepl" is the following
: 

On the first DC, INBOUND NEIGHBORS : 

Last attempt @ Wed Feb 4
11:26:41 2015 CET failed, result 58 (WERR_BAD_NET_RESP)
235 consecutive
failure(s). 

On the same DC, log level at 5, we've got the following
errors trying to force replication : 

The command : 

./samba-tool drs
replicate FirstDC SecondDC dc=fhm,dc=local 

The result in the samba log
: 

 ldb: No objectClass found in replPropertyMetaData for
CN=gastroenterologie_sADEL:dd657361-ee30-409c-a8fe-388884a55e6a,CN=Deleted

The
replication works one-way, from FirstDC to SecondDC 

Note that the
"samba-tool checkdb" return no errors on both DC. 

Is there a way to
clean the corrupted database on the DC which seems not working properly
? 

Thanks a lot in advance for your help. 

Cheers,
