My notebook running linux is already authenticating against the win. domain (AD). I've done this using samba,
kerberos5 and winbind (pam modules etc), thats woring perfectly :-)

Now, what i need : my desktop (that is another linux machine) authenticanting against my notebook, using samba,
but the problem is that samba is already configured @ the notebook as a AD Domain member :S.

Well, the principal service is a VMWare GSX Server running on my notebook, i need to be able to authenticate
(using the vmware-console) from any machine in my network (windows or linux). I think the vmware thing is the
less important part, cause it should be easy editing pam.d/vmware-authd after everthing is configured.

I want to have bgola on the linux machine for a control propose, or, only authenticate if the user exists on
the machine. This is already working for console/ssh/etc on the Notebook.

Resume: I need to transform my notebook (that is a AD Domain Member) in a Auth server, but with out leaving the
AD Domain Member status, because it will need to get the passwd for some accounts from the AD Server.
