samba - Jul 2002 - NT user name resolution to UNIX user name doesn't work the same

My departmental file server is on RHL6.2(i386) (Samba 2.0.6) and participates in
the company's NT domain. If an NT user wants to see shares on this
UNIX(Linux) box I have only to create a UNIX account for them where the UNIX
username matches the NT username. I have a Solaris 8 box (Samba 2.2.2), I cannot
figure out how to make it act the same way. I have looked at winbindd but that
does noot seem to do what I want. What I do not want to do is maintain a
smbpasswd file.

yes

This is the desired behavior, i.e. nothing (not much) in the smbpasswd file.
ergo If your NT username doesn't match up to a UNIX user (i.e. NT login =
"jbloggs" == UNIX login = "jblogs") then no access.

no, (I read the FAQs) I used "smbpasswd -j domain -r pdc -U
Administrator" to join the domain. And when I look at the domain
administrator thingy on the PDC the solaris box is on the list. I am having to
add the user (a user that exists in the UNIX world (nis) and the NT world
(domain)) to the smbpasswd file- I dont want to do this and don't have to on
the linux box.

Is the NT user being resolved as "domain/user"? If so how do I default
prefix a domain name? I do not want to wind up with UNIX usernames like
"billsworld/jbloggs".
