12:59 p.m.
I am following the directions from here:
Section: 32.6.4. Configuring DNS forwarding in AD
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/...
I get an error message from AD DNS "The server with this IP Address is not
authoritative for the required zone"
This error makes me think there is a problem with my IdM DNS server.
My setup is AD integrated and a one way trust is established with AD. I was able to
create a forwarder from IdM to AD without issue.
My domains:
AD = gsil.mil
IdM = idm.gsil.mil
I have been reading:
86.1. Supported DNS zone types
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/...
and
6.1. The two roles of an IdM DNS server
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/...
as well as several articles on DNS forwarding vs DNS delegation for AD.
This is a step that I was able to make work with no issues in a previous
setup/installation.
Red Hat documentation states:
86.1 Supported DNS Zone Types
"Forward DNS zones
From the perspective of IdM, forward DNS zones do not contain any authoritative data.
In fact, a forward "zone" usually only contains two pieces of information:
- A domain name
- The IP address of a DNS server associated with the domain "
6.1. The two roles of an IdM DNS server
By default, the Berkeley Internet Name Domain (BIND) service integrated with IdM acts as
both an authoritative and a recursive DNS server:
Authoritative DNS server
When a DNS client queries a name belonging to a DNS zone for which the IdM server is
authoritative, BIND replies with data contained in the configured zone. Authoritative data
always takes precedence over any other data.
I am still having some confusion why this is not working. Can someone enlighten me?
