samba - Jan 2003 - interdomain authorization with samba-3.0alpha20

Hello 

I am  trying to allow win2k and nt4 users from 2 domains , d1 and d2 to access
shares on a tru64 v5.1A server
using samba-3.0alpha20. 

Setup:
====
1.	there are 2 domains ,d1 and d2 with trust relationship established
2.	d1 is a w2k domain and d2 is an nt4 domain
3.	samba on the unix server has the following parameters set:

	security = server
	password server = pdc_d1
	workgroup = d1

4.	Users from d1 can map shares on the unix server OK, users from d2 cannot.
	The samba log says:

[2003/01/21 11:36:45, 0] passdb/pdb_smbpasswd.c:(1350)
  unable to open passdb database.
[2003/01/21 11:36:45, 1] auth/auth_server.c:(359)
  password server pdc_d1 rejected the password
[2003/01/21 11:36:45, 2] auth/auth.c:(271)
  check_password:  Authentication for user [MAMORO] -> [feed_it] FAILED with
err
or NT_STATUS_LOGON_FAILURE
[2003/01/21 11:36:45, 2] smbd/server.c:(533)
  Closing connections

	MAMORO is an d2 account

5.	Using samba settings

	security = server
	password server = pdc_d2
	workgroup = d2

	users from d2 can map shares but users from d1 cannot

6.	A d2 user can successfuly access shares on a w2k server in domain d1

7.	I played around with security=domain but with no success.

Finally:
Thanks for reading this line. I am new to samba and I spent a week grepping for
possible recommended settings in the inet
and samba mail lists. ANy hint/suggestion/question is welcomed

Thanks for your time
