1. The Certificate On My Yubikey was issued by the IPA server CA, since it's my domain controller it makes sense to keep it the CA.

2. I don't use mapping rules and matching rules, and I went through a WHOLE PROCESS to get the 'clientAuth' key on my cert.

3. On my IPA Server it gives 'PKINIT is enabled
The ipa-pkinit-manage command was successful'

Noted, I'll hit 'reply-all' from now on.

Looking over those links you sent me, I've decided to:

- Ran 'ipa user-show $user' and verified the certificate returned

- Ran 'ipa certmap-match cert.pem' on an extracted certificate that is also on the SmartCard, it returned my user.

- Ran 'kinit' and it reacted to my smartcard being present, asking for a PIN along with my username being displayed, giving the default pin of '123456' it returned an error I haven't been able to decipher yet:

'kinit: KDC policy rejects request while getting initial credentials'

I think this is the current blocking point in the authentication process, any ideas what it fully means? My google-fu has failed me here.

There are a few additional things to check.
1. Was the certificate on your smart card issued by IPA CA or by a different CA? If it was issued by a different CA, this CA must be trusted and this is achieved by running the preparation steps for the server:
kinit admin
ipa-advise config-server-for-smart-card-auth > config-server-for-smart-card-auth.sh
chmod +x config-server-for-smart-card-auth.sh
./config-server-for-smart-card-auth.sh issuingca.pem

Do not forget to execute ipa-certupdate on all IPA machines (server, replica, clients).

2. If you don't use mapping rules and matching rules, the default applies and SSSD ensures that the certificate from the smart card contains the Extended Key Usage “clientAuth”. Does you certificate have this EKU?

3. Is the ipa server properly configured for pkinit? What is the output of
ipa-pkinit-manage status

Please keep responses on the list.

The log to see depends on the behavior.

Some additional readings (some are rather old but still relevant):
