[Samba] to know which dns-backend ?

Thu Oct 13 12:35:46 UTC 2016

Hello guys: 
I need to know a strategy to identify which dns-backend are Samba4 DC using: BIND9 or Internal? 
Some time ago someone told me I can check this by verifying if exists the user 'dns-hostname'. 
But, what if this user has been deleted? 
Or, what's the situation if I need to get the dns-backend on a replication environment? 

On the other hand, How can I know if my server is running Samba4 AD? I mean I need to automate this process, so first I've to do is check if Samba4 AD is already installed. 

Thanks,
