samba - Aug 2002 - Which Samba Version for winbind and Solaris 9

Hi Group!
I want to install a new fileserver in our office.
We have:
- A Win NT 4.0 PDC
- A Sun Server with Solaris 9 installed

We need:
- The SAMBA Fileserver should use the Win PDC for User Authentification

It's possible to authentificate the user only by the PDC and map the access
of all authorized (nt)user to a single (unix)user ?

Greetings

Markus
