[Samba] Internal DNS and recursion

Thanks Rowland and everyone else that responded. I just didn't expect 
the AD tool to work with Bind, so that's a pleasant surprise. Looks like 
I'll be switching to Bind then. I must say that given that (according to 
Microsoft) DNS is the single most important component of Active 
Directory I'm surprised it's so very unfinished in Samba 4. I believe it 
would be preferable to have it default to external Bind and it should be 
clearly stated that the internal DNS is not production ready.

Can anyone tell me whether or not the version of Bind in the CentOS 7 
repos is suitable for this purpose or do I have to build from source?
