security=server should be discouraged, but I do not intend to drop it
from Samba4, going forward.  

This mode of operation (the active MITM attack) has it's problems, but
where you do not have the active cooperation of domain admin, there are
few other options.  (And some people really are in the situation where
the central admins don't mind password checks, much like 'ldap
authentication', but won't give out domain member accounts).

In Samba3, with clients later than NT4 are actually quite reliable with
security=server, because the use of NTLMSSP (extended security, SPNEGO)
removes the need for the long-term connection to the DC.
