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
; <<>> DiG 9.11.4-P2-RedHat-9.11.4-16.P2.el7_8.6 <<>> dc1.ad.cloud.chx NS ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 15346 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1

The other DNS server is up and running.
[root@ipa1 ~]# dig @192.168.1.253 dc1.ad.cloud.chx

This is worth noting that adding +norec works.
[root@ipa1 ~]# dig dc1.ad.cloud.chx NS +norec

Is there anything I'm missing?
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?
