Our case: example.com<http://example.com> (External DNS name with DNSSEC enabled) win.example.com<http://win.example.com> (Active Directory Zone) nix.example.com<http://nix.example.com> (FreeIPA Zone) Even with the correct conditional forwarders set up in Windows DNS and FreeIPA DNS, DNSSEC kicks in and fail resolutions. I _MUST_ disable DNSSEC? There’s another way? There are 'dnssec-validation' and 'dnssec-enable' options in /etc/named.conf. If you don't have DNSSEC configured and don't want to validate DNSSEC, turn them to 'no'. Thanks Alexander, but that’s the question haha. I don’t want to disable DNSSEC, but I can’t find a way to make it work. The problem in my domain is that the external DNS name is on CloudFlare Free Tier, so I don’t have the private keys. Is it okay to just sign the internal zones with a new key? This makes no sense for me, and should not work if I do get DNSSEC correctly. The only way to keep the external DNSSEC working, in my case, is disabling DNSSEC on IPA and AD, am I correct? -- / Alexander Bokovoy Sr. Principal Software Engineer Security / Identity Management Engineering Red Hat Limited, Finland
