As you realise already I think - it's nothing to do with FreeRADIUS,
which just runs the ntlm_auth binary and uses the result.
You need to run ntlm_auth manually with the same args, reproduce it
there, and then debug back up through Samba.
Once ntlm_auth works, FreeRADIUS should work, too.
From what I recall, you would normally link the domains together and
then just join the FreeRADIUS server to one domain, the DC it sends its
request to should forward to the other domain based on the --domain arg.
If you want to join to two distinct domains simultaneously I believe
you'll need to have two separate isolated instances of Samba running
(this may have changed since I looked last though).
