Wrong way around, a fileserver (what you are calling a domain member 
server) is a Unix domain member that has shares. It really doesn't 
matter what you call them, 'workstation', 'fileserver' or 'domain member 
server' etc, they are all Unix domain members and the basic setup is the 
same.

As long as you use exactly the same '[global]' section on all Unix 
domain members, they will all work exactly alike.

Oh, very much so ;-)
