Ignore the wiki and don't put anything in /etc/hosts, if (like on 
ubuntu) you have 127.0.1.1 pointing to your hostname, remove or comment 
out this line, but you really should give a member server a fixed ip

you need to use the internal DNS or bind DNS, you cannot use both.

This could be interesting, how are you going to authenticate the private 
network users to a machine that is joined to a domain?

The term 'member server' is a bit of a misnomer, it really should be 'a 
Linux client that serves files', any Linux client is basically set up in 
the same way, what you do with it after, is what defines its role.
