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:

Hi,
in the above output we can see 2 different certificates for
"CN=Certificate Authority,O=MATERNA-COM.DE", which is an expected
behavior: the database still contains the old one (Not After: Sat Jan 13
14:45:00 2018) but also contains the new one (Not After : Mon Jan 23
14:45:00 2023). So from this point of view, IPA CA cert was properly
renewed and distributed to the httpd NSS database.
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

2018-01-24 11:23:00 [1026] Internal error
The traceback is generated by the helper launched to renew IPA CA. This
helper authenticates using /etc/krb5.keytab but according to the traces,
was unable to reach the Kerberos server.
Can you manually try to perform
$ sudo kinit -kt /etc/krb5.keytab
and check its output?

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
