[Samba] samba internal DNS Zone transfers and notify for slaves?

[Jeff Sadowski]

I was wondering if I can implement slave DNS servers for a samba domain.
I would like to setup a slave section on my bind server that gets its
information from my samba-ad dns server?

Or is my only option at the moment to use bind-dlz with bind on my samba-dc?

This page:
https://wiki.samba.org/index.php/DNS_Administration

says zone transfers is unimplemented
but one of the links on there

https://bugzilla.samba.org/show_bug.cgi?id=9634

I see

Julien mentions authorized clients for DNS zone transfers?

Looks like this is in DLZ.
Wondering where to find examples to add authorized clients.
Looks like the Fedora developers are against using DLZ but I see no
alternative to have slave servers.
I want slave servers so that I can implement multiple domains.
