[CentOS] Linux kerberos to Windows AD 2000/2003

I have spent the last 4-5 hours scrounging google articles on this and
have found 2 solutions. The problem is one of them is something that we
will not do (as MS will not support extending AD with Services For
Unix(SFU)).
 
The other is simply configuring kerberos and pam on the linux system. No
problem there from what I can tell.
 
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: userid at dom.ain
 
Valid starting     Expires            Service principal
07/05/06 07:23:03  07/05/06 17:23:47  krbtgt/DOM.AIN at DOM.AIN
        renew until 07/06/06 07:23:03
 

Kerberos 4 ticket cache: /tmp/tkt0
klist: You have no tickets cached
 
 
The problem though is configuring winbind from the console (all of the
linux systems are nothing more than the kernel, ssh and the few apps
necessary for the system to do it's job). All the online examples I have
been able to find use the linux GUI. 
 
Does anyone know of a document (or mind sharing) how they installed and
configured the samba 3 winbind daemon to map SID's to unix uid's/gid's?
That would eliminate the need to extend the active directory schema.
 
thanks,
 
Greg
