[Freeipa-users] DNSSEC warning when DNSSEC should be disabled

My configuration is a single ipa server and both the code path and the bash prompt path are running on the node that is also running the ipa server. I thought that since FreeIPA was installed with --no-dnssec-validation that I should never see this warning. And I confirmed that both dnssec-enabled and dnssec-validation are set to 'no' in the /etc/named.conf.
So I'm confused that you say the DNSSEC should always fail.
Thanks for your help!

I am seeing inconsistent results configuring a DNS forward zone.
At a bash prompt, as root, after kinit admin, I do:
ipa dnsforwardzone-add domain.internal --forwarder= ww.xx.yy.zz --forward-policy=only
That works fine and does not warn about DNSSEC.
In a Java webapp running as root under a Jetty, I run a shell sub-process and issue the kinit and the same ipa statement.
_Sometimes_, I get
ipa: WARNING: DNSSEC validation failed: record 'domain.internal. SOA' failed DNSSEC validation on server ww.xx.yy.zz.
Please verify your DNSSEC configuration or disable DNSSEC validation on all IPA servers.
I modified the /etc/named.conf file to say:
dnssec-enable no;
dnssec-validation no;
and systemctl restart ipa
Any clue why the results are different?
ipa –version: VERSION: 4.4.0, API_VERSION: 2.213

Thanks for any insight!

Hello,
checks are done on IPA server side, how many servers do you have? Is possible that CLI connects to different servers.
However in this case, DNSSEC check should always fail and report error, so it is weird why it passed.
