Comment 8 for bug 1357471

I can confirm that applying the patch provided in https://bugzilla.samba.org/show_bug.cgi?id=11164 does not fix the issue.

The "Did not manage to negotiate..." error message is gone but the other message "Failed to bind..." still spams the logs and replication is broken as per "samba-tool drs showrepl".

I can also confirm that what triggers this are network connectivity interruptions between the DCs. After connectivity is restored, replication is not reestablished until Samba is restarted
