samba - Jun 2014 - Samba4 Domain controller - PTR records with/ DNS not being created

Hi, all:

This is my setup:

Single domain with 2 x Samba 4.1.6 Domain controllers. I created the
reverse zones in DNS with Micro$oft's DNS admin tool. Zones are there.
However, when a machine is joined to the domain, the forward DNS record is
created but the reverse ones are not.  I am using samba's internal DNS
server. Any on what I need to do?

Thanks,


E.
