[Samba] Seperate BIND server for Samba 4

[Amaru Netapshaak]

Hello!

I've set up samba 4 with great success since alpha12, but i've always used a 
locally installed version of BIND.  

Is it possible to use a seperate BIND server instead? I'd like to not run BIND 
on my file server.

I have not seen any instructions to this effect, so perhaps someone would please 
point me in the
correct direction?  

Thank You Very Much!!
