[Samba] winbind design query: why does ntlm_auth work when the same
auth via smbd fails?

I have an issue with being unable to successfully allow any user from
trusted domains to connect to an ADS Samba-3.0.24 server (joined via
kinit && net ads join)
Our AD (Win2K3 based) domain is "OURDOM", and Samba is a member of it.
Access from OURDOM accounts is 100% fine. However (2-way trusted)
username "TDOM\user1" cannot connect to an open share on it, and yet
"ntlm_auth --username=user1 --domain=TDOM" successfully authenticates!
I have seen this several times before under different Samba releases,
and have seen others report it on this list too. Typically the logging
shows the smbd connection coming in as "[TDOM]\user1" - but suddenly the
domain gets dropped, and "user1" is authenticated - incorrectly -
apparently against the OURDOM domain (which will obviously fail)
Can someone explain why ntlm_auth could possibly work (it implies
winbind is totally happy?), whereas smbd should return Access Denied?
And yes, "allow trusted domains = Yes" is set.
