I'm having an issue delegating a subdomain. My domain is cloud.chx and I ran the following.
ipa dnsrecord-add cloud.chx dc1.ad --a-rec=192.168.1.253 ipa dnsrecord-add 1.168.192.in-addr.arpa. 253 --ptr-rec=dc1.ad.cloud.chx. ipa dnsrecord-add cloud.chx ad --ns-rec=dc1.ad.cloud.chx.
I checked and it's in the config
[root@ipa1 ~]# dig axfr cloud.chx | grep ad ad.cloud.chx. 86400 IN NS dc1.ad.cloud.chx. dc1.ad.cloud.chx. 86400 IN A 192.168.1.253
But when I query, it doesn't return what I expected.
[root@ipa1 ~]# dig dc1.ad.cloud.chx NS

Do you have the validating resolver(DNSSEC-aware recursive server) listening on 127.0.0.1#53? And if Yes then do you have DS RRs in the parent zone for the delegated one?

I believe what you're seeing is normal behavior. If you ran that query against a TLD you'd get the NS servers of the TLD in the answer section but I don't believe it works that way when delegating subdomains.
I just tested in my environment and when I query an a-record in the delegated subdomain the proper NS records appear in the authority section but I do not get a response querying for NS records directly against a delegated subdomain.

I believe what you're seeing is normal behavior. If you ran that query against a TLD you'd get the NS servers of the TLD in the answer section but I don't believe it works that way when delegating subdomains.

Shouldn't my TLD tell the client where to get that record though?
In my case I have cloud.chx and I delegated ad.cloud.chx to my Windows DNS server.
When a query comes to the NS of cloud.chx it should get that answer from the NS of ad.cloud.chx right? There's something I must be missing on the IPA side because when I try this setting from a BIND to BIND set up...it works as expected.

I think I see it now. The A record that your NS record points to should be a record within the cloud.chx domain, not the ad.cloud.chx subdomain.
So you could do something like this:
ad-ns1.cloud.chx 86400 IN A 192.168.1.253 ad.cloud.chx. 86400 IN NS ad-ns1.cloud.chx.
Then if you query an a record in the subdomain (e.g. test.ad.cloud.chx) you should see the NS record in the authority section.
