samba - Feb 2004 - trust relationship: samba PDC & AD in Native Mode

Hi all,
I'd have a question: is it possible for a Samba3 server acting as PDC
(or AD) for clients win95-98, NT to establish a trust relationship with
an Active Directory Win2k working in Native Mode?
The aim is to give some old Clients access to some servers belonging a
modern AD domain.
 
I made some tests but could not get through. I'm doubtful this may work
at all at the status of the art. 
I would appreciate any positive insight (or link) to get motivation
querying the matter (or to leave it at all..)
Thanks so much,
Gian
