I don't think so, since Samba isn't really tied to the group membership 
like you are thinking... (though I would want a Samba team member to verify 
that for me to be sure :-)

This below is from another thread, but sounds like it is exactly what I
was looking for....
My question is, couldn't the linux groups file be used , or smbgroups be
implemented into samba, where we have some native support for this....

I think simplifying this is really needed for SAMBA.

Subject: Re: [Samba] Group Login Scripts in Samba 2.2.3?

I used a slightly different approach to solve this problem using a 
single login script. The solution is in two parts

On the Linux/Samba side use a pre-exec script in the netlogon share 
to create a text file of the groups the user is in

i.e groups > /home/%u/grouplist.txt 

and a post-exec script in the netlogon share to delete this file on 
logout 

i.e rm -f /home/%u/grouplist.txt

On the windows side I created a small program in C that read the file 
(grouplist.txt) (accessable via the 'homes' share) and used an exit 
vale of 0 or 1 to confirm if a particular group was included in the 
list. I used this program from within the login script and the DOS 
ERRORLEVEL command to branch depending on wether the user was a 
member of the requested group. The command line parameters to the 
program where the group being checked, and the name of the text with 
the group listing in it.

The login script used lines like this (my prog was called member.exe)

Z:\member \\servername\homes\grouplist.txt staff
IF NOT ERRORLEVEL 1 goto (next part of login script)
do stuff here for members of staff group

I stored the member.exe prog in the netlogon share hence the Z: 
reference.

We use this approach on a school lan with about 150 users and no 
problems to date (after 15 months of use).

If this is of any use I can supply the executable and C source code 
on request.

I have been using ifmember.exe for several years.  It works great for
NT/2k
clients, but will not work with 9x clients.  Major drawback.  A perl or
kixtart script would work much better in handling this if you need to
support Win9x clients.
