new get_any_dc_name() function allows lookups of trusted domains from
lp_trusted_domains() parameter, so trusted domain logins should work,
right, if you put user = TRUSTED_DOMAIN\NTuser in "domain name map", right?

right - as _long_ as you're not using NTLMv2, because the damn NT username
gets mapped to the damn unix name too early, and NTLMv2 challenge-responses
are based on the client's user name, client's domain name, client's host name
etc damn etc.

so it becomes necessary to stop using char* username because this allows
for massive amounts of confusion as to which username is being referred to.
the underlying unix username on the local unix system that is associated with
the smbd process that represents the NT username?  or the NT username itself?
