There are two issues:

a) The workstations log on to another domain, managed by AD, and I don't 
want to integrate Samba with that domain

b) I want each Samba server to be able to operate independently, but 
give the users the convenience of a single password for all servers

I'm quite happy to create a Samba PDC, but if I can just make the Samba 
servers operate as standalone servers using a common workgroup name, is 
that more convenient to setup and more fault tolerant?
