Hi,



I seem to have issues with the certificate system on my IPA installation. Looking up hosts in the IPA WEBUI on any of the IPA servers says "Certificate format error: [Errno -8015]
error (-8015)
unknown".

I also notice that hosts says the certificate system is unavailable.



certmonger: Server failed request, will retry: 4301 (RPC failed at server. Certificate operation cannot be completed: Failure decoding Certificate Signing Request).


Looking at the pki-ca logs on the ipa servers I see that some selftest failed:

My main consern is that the certmonger requests for renew of certificates for LDAP on 2 out
of 3
of the IPA servers has failed, and the current certificate is expiring the 19th of January,
under a week from now.

Do you have any suggestions to where I can start troubleshootng this issue?



Check the trust on the audit certificate:



# certutil -L -d /var/lib/pki-ca/alias/
...
auditSigningCert cert-pki-ca                                 u,u,Pu

If the trust is not u,u,Pu then you can fix it with:



# certutil -M -d /var/lib/pki-ca/alias -n 'auditSigningCert cert-pki-ca'
-t u,u,Pu



Then restart the CA and it should be ok.



Looks like this certificate is expired. This is the same output on all 3 of the ipa servers.


How can this be fixed?



# certutil -L -d /var/lib/pki-ca/alias/ -n "auditSigningCert cert-pki-ca"
Certificate:
Data:
Version: 3 (0x2)
Serial Number: 5 (0x5)
Signature Algorithm: PKCS #1 SHA-256 With RSA Encryption
Issuer: "CN=Certificate Authority,O=DNS.DOMAIN"
Validity:
Not Before: Thu Jan 19 19:44:24 2012
Not After : Wed Jan 08 19:44:24 2014




Go back in time to the 7th or 8th and run:


# getcert resubmit -d /var/lib/pki-ca/alias -n "auditSigningCert
cert-pki-ca"

There may be other certs in a similar situation. getcert list will show you.



Ouch. That would be rather disruptive I suppose. There is quite a lot of activity going to this server, not to mention it's the primary ntp and dns server for the network.

Do you suppose this todo list will work ?

Firewall off the rest of the network, leaving the ipa server alone
Stop ntpd
Set date to 8th of January
Run the getcert resubmit command.
Change date back to correct date
Start ntpd
Remove the firewall rules

Looks good. I'd restart the certmonger service rather than resubmitting each individually. Be prepared for renewal to not succeed. For some reason it didn't on and before expiration time so whatever problem existed then likely still remains.

So the question to ask is "what will I do if renewal fails again?"

Nothing catastrophic will happen, but it will likely mean having to roll forward again, debug, roll back, try again, and perhaps more than once. It's hard to say w/o knowing why it failed in the first place.

How many of the services is required to be restarted for the renewal to work after the date is
changed to the 7th?

The renewal itself should restart the required services.


This worked better than expected. Thank you! :)

ipa01 and ipa02 seem to be happy again, "getcert list" no longer displays any certificates out of date, and all certificates in need of renewal within 28 days has been renewed. The webui also started working again and things seem to be back to normal.

ipa03 however is still having issues. I could not renew any certificates on this server to begin with, but I managed to renew the certificates for the directory servers by changing the xmlrpc url to another ipa server in /etc/ipa/default.conf and resubmitting these requests.

"getcert resubmit -i <request-id" says SUBMITTING and the fails with NEED_GUIDANCE after a short while for the certificates for the PKI service.

/var/log/messages says: "certmonger: #033[?1034h28800" and "python: Updated certificate for ipaCert not available".

There is a lot of information in the /var/log/pki-ca/debug, but nothing that I can easily distinguish as an error from all the other output. Anything in particular I should look for?

Siggi
