Hi experts ,

Is it possible to have automated population of Reverse PTR  on Samba 
4.4.5 integrated with Bind 9.9.4 ? I have tried creating the Reverse 
zone too . When a client ( windows ) joins the SAMBA domain the forward 
lookup is populated with correct host-name and present IP , but reverse 
zone does not have any entry . Although I can create reverse PTR manually .

Kindly help me with this query

Attaching named.conf for reference.

         - If you are building an AUTHORITATIVE DNS server, do NOT enable recursion.
         - If you are building a RECURSIVE (caching) DNS server, you need to enable
         - If your recursive DNS server has a public IP address, you MUST enable access
           control to limit queries to your legitimate users. Failing to do so will
           cause your server to become part of large scale DNS amplification
           attacks. Implementing BCP38 within your network would greatly
           reduce such attack surface
