[Bug 1357471] Re: Samba4 AD DC randomly dies, error: "Did not manage to negotiate mandetory feature SIGN for dcerpc auth_level 6".

[Jorge Albarenque]

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
