DNS Zone Transfers

I have 3 Windows AD (2K8R2) Based DNS Servers that are the authoritative for our domain.local zone.  Also in the environment we have a Linux DNS server as well that is the authoritative for our domain.com zone.  

For the windows servers they have two zones, domain.com and domain.local.  Domain.com is a secondary zone.  For the domain.local zone, the zone transfers is set to any, to replicate to the linux dns server.

Here is the issue:
We recently started using Nessus for vulnerability and compliance scanning.  Nessus is suggesting to limit zone transfers to only the servers that need the information.

So my options are: only servers listed on the Name Servers tab or only to the following servers.
When I try to add the linux server to the name servers tab I get a message, "the server with this IP address is not authoritative for the required zone."  I get why I get the message since the linux server doesn't have authoritative over domain.local but what is the correct way to make nessus happy and still allow zone transfers from .local to the linux server?

Do I enter the linux dns server ip into the 'Only to the following Servers' and if that is the way do I need to include the other AD servers?

thanks in advance

Yes and Yes. Once you have Zone transfers allowed, you can configure the domain.local zone as a secondary on the Linux server.

so the message: the server with this IP address is not authoritative for the required zone.

can be ignored since the on the linux server the domain.local is just a secondary zone??

Yeah. That shouldn't pop up if you add it to the list of servers in the Zone Transfers tab. The Name Servers tab is there to assign Primary DNS Servers. The only servers that can be added there are Domain Controllers if the Zone is AD Integrated, which it probably is.

I didn't think it would either but it does pop up on the zone transfer tab > only to the following servers.  Once I enter the Linux server IP I get the message, "the server with this IP address is not authoritative for the required zone"

You are correct the domain.local zone is AD integrated and the name servers tab has the 3 DCs listed.  Also the domain.local zone is setup as a secondary zone on the Linux DNS server.

I guess I want to make sure I am not missing anything since I am still getting that message
