Thanks.  It wasn't clear if you were an AD client or server.  You have a
domain member server in an AD domain running Windows 2012 on the DC.

You will need to either upgrade to Samba 4.2 or set 'client max protocol
= smb2'.  I recommend the upgrade, as our SMB2 RPC client and the
handling require in winbindd is more mature in more recent versions.

In all versions SMB2 is disabled in the client by default, but in 4.2 we
make an exception for winbindd, which runs up to SMB2 by default.
