Hello IPA-experts,

we are running FreeIPA version 4.4.0 with an external CA (our own one), everything was working fine until the CA certificate expired which happened at January 13th. Since i was on vacation and the basic functions were still available no-one created a new certificate, so, it's now my task. As explained in https://www.freeipa.org/page/Howto/CA_Certificate_Renewal, I've reset the time to January 10th, created a new certificate which is valid from 2017 to 2023, and installed it with ipa-cacert-manage. Afterwards, I did an ipa-certupdate, the server certificates were updated and the cert8.db in /etc/httpd/alias contains the new valid CA. But, the expiration date of the certificate itself is still January 13th, so, the certificate is still expired:

I have only checked this one, but I'd suppose the others are also not updated. AFAIK certmonger is responsible the renewal, so, I've restarted it and hoped it would grab my certificate and renew it - but it seems there is a problem, journalctl -u certmonger gives

Any help is greatly appreciated since I'm stuck here... If it helps, I have a clean backup of the IPA master which was written yesterday evening, so, I can use this one to "start over" if I've already mixed up things.

Thanks and kind regards from Germany,

Harald
