Thanks for speaking up, Harry! :-)

For Samba users (real actual users) there is an entry in passwd and group. I would think I can use adduser to set those up, and edit the uid/gid # to match.

For Samba machine users, there seems to be only an entry in passwd, and shadow of course. The password hash appears to be the same hash as other ID's which no one ever logs into. So I would think I 
would be safe hand editing both passwd and shadow to add the machine accounts, and simply copy/paste the password hash that is appropriate for the new server.

Do you see any problems with this course of action?
