[Samba] Replication issue (maybe due to 4.7.0 bug?)

[Gaetan SLONGO]

Hi Andrew, 


By increasing global logs (not only drs) I get this : Failed to apply records: ../source4/dsdb/samdb/ldb_modules/repl_meta_data.c:3643: Failed to remove backlink of msDS-RevealedDSAs when deleting CN=DMZRODC 




Full log for this object :

You need to turn up the logs on the destination server until you get 
more useful log entries leading up to: 


==> /var/log/samba/log.samba <== 
[2017/12/07 10:10:55.825907, 0] 
../source4/dsdb/repl/drepl_out_helpers.c:942(dreplsrv_op_pull_source_ap 
ply_changes_trigger) 
Failed to commit objects: 
WERR_GEN_FAILURE/NT_STATUS_INVALID_NETWORK_RESPONSE 

I hope this helps, 

Andrew Bartlett
