Ah, I see! I modified the wrong table, thank you for noticing that.

These two should not make any difference in our case. (They indicate that the
keys were not created inside the HSM in question and could possibly be exposed
in plain text somewhere.)

Now it is getting interesting :-)

First of all, what version of FreeIPA packages and on what distro are you
using? There are significant differences between package versions.

The export is handled by ipa-ods-exporter service on IPA DNSSEC key master
server. Look at its logs and see if it reports any errors.

I'm not sure how OpenDNSSEC handles key import. IPA is waiting on OpenDNSSEC
signer's socket for events which indicate key state change. If this does not
happen the key is not exported.

You can trigger this manually by calling command
"ods-signer ipa-full-update"
or
"ods-signer update <zone name>"

Watch the ipa-ods-exporter service logs when you run this command and watch
out for any problems. You might add debug=True to /etc/ipa/default.conf if you
need to see more details about the process.
