[Bug 1592397] [NEW] Samba domain broken by 4.3.9 update on Trusty

[Pierre Pouchin]

Public bug reported:

I have set up a samba domain using an LDAP backend a few years ago.
The primary domain controller is under Debian Jessie.

Whenever I try to update my domain client server (under Ubuntu Trusty),
I get NT_STATUS_NO_LOGON_SERVERS while trying to access a share (on the
Trusty server) from a computer.

Reverting back to 4.1.6 fixes the problem, but it is not a viable
solution.

There are other servers that are part of this domain (with Debian Jessie
and Ubuntu Precise), but these work fine, although I needed to tweak the
signing parameters for Precise.

I tried adjusting several parameters on Trusty (require strong auth,
client ipc signing) but to no avail...
