[CentOS] Centos 7 Bind and DLZ support

Is DLZ support enabled in the Centos 7 bind?

building a Samba/sernet AD, and this looks to be the best way to handle 
the DNS needs of the AD.

thanks.

Also any web tools for managing a mysql (mariaDB?) DLZ backend? Web, as 
my AD will not have a GUI; nor should I be doing this on the AD directly.
