- Subject: [Samba] samba 4.7.0 replication errors
we have 5 ADDCs. All of them did run with sernet-samba 4.6.7.
I updated 4 of them to sernet-samba 4.7.0, one after the other, checked replication, everything seemed to be ok.
One day later a colleague wanted to delete a lot of users with a powershell-script and since then the
replication doesnt work anymore. (Im sure the script is not the problem, but it seemes like it triggered something)
All samba-servers with version 4.7.0 report errors with at least one other ADDC like
Default-First-Site-Name\ISAMBA4-2 via RPC
DSA object GUID: 5dc32731-e914-486d-96f1-ce065ff956bf
Last attempt @ Fri Sep 29 10:37:24 2017 CEST failed, result 58 (WERR_BAD_NET_RESP)
358 consecutive failure(s).
Last success @ Thu Sep 28 10:18:16 2017 CEST
The command "samba-tool dbcheck --cross-ncs --fix --yes" reports hundreds of errors like
ERROR: orphaned backlink attribute 'memberOf' ...
The dbcheck-command says, it fixed the problems, but when I execute again, a lot of the same error comes again ( I can not say, if the same entries are effected).
The log.samba has a lot of entries like
[2017/09/29 10:26:15.502219, 0] ../source4/dsdb/repl/drepl_out_helpers.c:959(dreplsrv_op_pull_source_apply_changes_trigger)
Failed to commit objects: WERR_GEN_FAILURE/NT_STATUS_INVALID_NETWORK_RESPONSE
If I make the dbcheck on the last server with version 4.6.7, this errors dont appear.
How do I get the replication to work again ?
Is the error "orphaned backlink attribute" the reason, why replication doesnt work anymore ?
And if so, do I have to fix all groups manually like said in a similar problem from the post "Samba 4.7.0 replication issue: failed get spanning tree edges" ?
