Subject: [PATCH] s3:winbindd: fix "allow trusted domains = no" regression
add_trusted_domain() should only reject domains
based on is_allowed_domain(), which now also
checks "allow trusted domains = no", if we don't
have an explicit trust to the domain (SEC_CHAN_NULL).
We use at least SEC_CHAN_LOCAL for local domains like
BUILTIN.
