[Samba] Samba server joining domain and browsing group shares

Hello I have a small network and would like to add samba to our environment. 
This what I would like to accomplish:
- We have a ADS PDC ( windows 2000 server)
-  We have 27 workstations windows XP-PRO

We have recently bought a new server, and installed OPENSUSE 10.3 and we have 
installed and configure samba. Basically we want to use the new samba server 
as a data repository server. 

In the windows environment we have 4 groups, management which has 4 users, 
Accounting which has 5 users, sales which has 3 users and ingeneering that 
has  15 users.

we would like that the users in each group only have access to the files for 
their corresponding group in the samba server. i.e accounting sees the 
accounting share only etc. this groups are defined in the PDC ADS machine not 
in the samba server.

My question is how do I configure the samba server to inherit the groups 
defined in the windows PDC ADS machine.

I  Include a copy of the /etc/samba/samba.conf file:

 # smb.conf is the main Samba configuration file. You find a full commented
# version at /usr/share/doc/packages/samba/examples/smb.conf.SUSE if the
# samba-doc package is installed.

The problem that we have is that users in the domain cannot logon into the 
samba machine and browse their group shares. 

Any help will be appreciated, we are really trying to move away from windows 
and solving this could help us convince management that this is the way to
