Multiple AD without trust AND authoritative DNS server

[jpujol]

Hi,

The ISE 2.3 admin guide and the following doc : "Active Directory Integration with Cisco ISE 2.x " both state that :

Cisco ISE supports multiple joins to Active Directory domains. Cisco ISE supports up to 50 Active Directory joins. Cisco ISE can connect with multiple Active Directory domains that do not have a two-way trust or have zero trust between them.

and at the same time :

recursive DNS server is not supported by Cisco ISE.

Since the authoritative DNS server for a domain is co-located with the domain controller, a single DNS server cannot be authoritative for all independent AD domains.

Can you give an explanation about the way to configure a central DNS server authoritative for several non-trusted AD domains ?

thanks,

Jean-Francois

I am reaching out to our team as it does not seem right to me. I think the main points are to ensure efficient DNS infrastructure and to properly secure it.

I've re-opened the doc bug CSCvc74150 and asked for re-wording.
