[Bug 1357471] Re: Samba4 AD DC randomly dies, error: "Did not manage to negotiate mandetory feature SIGN for dcerpc auth_level 6".
I recently compiled and installed Samba v4.3.1 on Debian Jessie (from the experimental repo) and I can confirm that this problem seems to have been resolved (at least on that version, although probably since on v4.2.x) -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in Ubuntu. https://bugs.launchpad.net/bugs/1357471 Title: Samba4 AD DC randomly dies, error: "Did not manage to negotiate mandetory feature SIGN for dcerpc auth_level 6".

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 -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in Ubuntu. https://bugs.launchpad.net/bugs/1357471 Title: Samba4 AD DC randomly dies, error: Did not manage to negotiate mandetory feature SIGN for dcerpc auth_level 6.

My two Samba AD DCs run in an environment with frequent network interruptions due to power cuts. It seems that even very brief network interruptions trigger this issue, which then doesn't resolve itself when connectivity is restored. After most network interruptions, the following three messages repeat in log.samba every 5 seconds, and 'sudo samba-tool drs showrepl' shows failures. A 'sudo service samba-ad-dc restart' is required to get everything working again. - Update failed: Miscellaneous failure (see text): Matching credential (GC/{other-dc}.{domain}/{domain}@{DOMAIN}) not found - Did not manage to negotiate mandetory feature SIGN for dcerpc auth_level 6 - Failed to bind to uuid {uuid-1} for {uuid-1}@ncacn_ip_tcp:{uuid-2}._msdcs.{domain}[1024,seal,krb5] NT_STATUS_ACCESS_DENIED. In a country with on average 12 powercuts *per day*, which despite a huge arsenal of stabilisers and UPS-es do cause brief network interruptions, you can imagine that this issue is a major pain in the behind :-/ -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in Ubuntu. https://bugs.launchpad.net/bugs/1357471 Title: Samba4 AD DC randomly dies, error: Did not manage to negotiate mandetory feature SIGN for dcerpc auth_level 6.

Thiago, Please don't subscribe me to bug email.

Hey guys! This problem still persist on Samba 4.1.11 from my PPA.

Guys, It is impossible to use Samba 4.1.6 from Ubuntu 14.04.1 as an AD DC in production. This is happening all the time: http://i.imgur.com/wDqOsy6.png I think that if you restart any Domain Controller, it will trigger this error on others DCs. Because I just restart my PDC (ubuntu-ad-1) and all BDCs dies. I just build an Ubuntu PPA Archive to provide Samba 4.1.11 for Trusty: http://launchpad.net/~martinx/+archive/ubuntu/ig - I'll test it today. Ubuntu needs a much, far much more serious Q.A.
