I'm not sure what options are available to you. But regarding my post : 
yes, this is about authorizing zone transfers in samba's bind DLZ module.

The code shipping in Samba today allows every zone transfers. The 
contribution I've made is adding an option in smb.conf to make it 
possible to limit it to selected IP addresses.

See https://gitlab.com/samba-team/samba/merge_requests/169.

It is not merged (yet?), so today you can't use this configuration.

Now whether DLZ is the best option for you - I can't tell. I'm not using 
Samba, just hacking on it on behalf of my clients.

Best regards,

>> Hi,
>> One of my clients asked for a fix on this issue. Seeing the comments on this thread, I implemented the suggested modification : add an option in smb.conf to control the list of authorized clients for a DNS zone transfer.
