Adding the "NSSEnforceValidCerts off" definitely got me past the HTTPD error. It started up and then I ran the systemctl start pki-tomcatd@pki-tomcat which seemed to start up without any errors (it didn't throw any on the command line), but checking the debug log I see I'm still getting the same, original "Peer's Certificate has expired" message for "Server-Cert cert-pki-ca". I just can't win 🙂 It's expired, I know it's expired, why does FreeIPA fight me so hard on just trying to renew it?! LOL!
Just for fun I then ran the "getcert renew -i <reqid>" command. But per "getcert list", it's still showing as CA_UNREACHABLE and Internal Error. Scott

"Unable to verify certificate 'Server-Cert'. Add "NSSEnfroceValideCerts off" to nss.conf so the server can start until the problem can be resolved", so maybe I'll try that.
That can work, just remember to revert it, but it just bypasses the start up check. Clients will still require cert validity.
I don't think it will matter either way as the CA certs renew directly against the CA so Apache not running shouldn't be an issue.

If your domain is domain.com, you need to run systemctl start dirsrv@DOMAIN-COM
I suspect that you ran instead systemctl start dirsrv@slapd-DOMAIN-COM which would produce the error you're seeing.

Not sure now how to proceed at this point.

Now when you say 'restart services', I assume you're only referring to the ipactl services? In that case I ran "ipactl start --ignore-service-failures". Interestingly, when I ran this command it not only failed to start pki-tomcatd (which I expected), but actually reset the date back to the present/correct time and date. Thus, I re-ran the command to set it back to Sept. 1st, 2019.
If the server was configured with ntp, "ipactl start" will also restart ntpd. You need to do the following: ipactl stop change date in the past systemctl start dirsrv@DOMAIN-COM (replace with your domain name) systemctl start krb5kdc systemctl start kadmin systemctl start named-pkcs11 (if IPA is hosting the DNS server) systemctl start httpd systemctl start pki-tomcatd@pki-tomcat
Then try getcert resubmit.
I then ran the "getcert resubmit -i <reqID> command. I just now went through these steps again, and it's showing "status: CA_UNREACHABLE" and "ca-error: Internal Error". Stuck now shows 'no'. Re-running "certutil -L -d /etc/pki/pki-tomcat/alias -n 'ServerCert cert-pki-ca' now yields a new error message, "certutil: could not find cert: ServerCert cert-pki-ca", and ": PR_FILE_NOT_FOUND_ERROR: File not found"
The cert nickname should contain a dash: "Server-Cert cert-pki-ca"

How did you roll the date back? Did you restart services? What date did you pick and does it overlap so that all certs are valid?

I backed up the files/directories you mentioned below, then I checked on the ra-agent.pem to see if it was still valid (openssl x509 -in /path/to/ra-agent.pem -text -noout), and the ra-agent.pem cert is indeed currently valid (Not before: Aug 21 17:20:41 2019 GMT, Not After: Aug 10 17:20:41 2021 GMT).
Based on that information, and knowing that the bad cert is valid from Oct. 6th 2017 to Sep. 26 2019, I'm going with Sept. 1st of this 2019 since all certs will see that date as valid.
The only issue I have now is getting the request ID for the expired cert; it doesn't show up in the list of certs when I do "getcert -list", I can only see it by running "certutil -L -d /var/lib/pki/pki-tomcat/ca/alias -n 'ServerCert cert-pki-ca'", and when I run that it does not show any Request ID associated for it?

I did notice when I compare it to another IdM server in the environment, if I do a "certutil -L -d /etc.httdp/alias" the non-working server has a <DOMAIN> IPA CA certificate and a Server-Cert, but the other one that I'm comparing against has a "Signing-Cert" certificate in addition. Is this because it's the 'Master' or whatever? Should my 'bad' server have this same Signing-Cert listed?
/etc/httpd/alias only needs its own Server-Cert + IPA CA.

Start by making a backup of /etc/dirsrv/slapd-*/*.db, /etc/httpd/alias, /etc/pki/pki-tomcat/alias and /var/lib/ipa/ra-agent.* (the places where the certificates are stored).
If the RA cert is valid, you need to find a time window during which the RA cert is already valid (date > notbefore) and the other certs are not expired yet (date < notafter). When you have identified a proper date, stop ntpd (or chronyd, depending on which service is used for time synchronization), move the date back in time to the identified date, start all the services except ntpd, then call "getcert resubmit -i <request id>" for the expired cert(s).
Check that the cert has been renewed with "getcert list -i <request id>", the state should display MONITORING. When all the certs are good, you can restart ntpd and the clock will go back to the current date.
It's really important to find a date where all the certs are valid because this ensures that the services are able to start and the RA cert allows the authentication that is mandatory for certificate renewal.
HTH, flo
Sadly, after I log in, it's only telling me that it's "Subscriber Exclusive Content". Not sure what happened with my account, I used to be able to access these docs with no problem but since I took a RHEL class a couple of weeks back now it's not working any more. I guess they did something to screw up my account when I took the class.

Thanks much for the assistance. Here is where I am with your suggestions:
- Checked on the cert with "certutil -L -d /etc/pki/pki-tomcat/alias -n
'Server-Cert cert-pki-ca' and I see that the Validity is indeed old (almost a year old actually, I assume IPA only checks it when it first starts up so it didn't care that it was expired until the server was rebooted?)
certmonger checks the certificate validity periodically (configurable in certmonger.conf) and tries multiple times to renew soon-to-expire certs. The system probably had an issue that was not detected and the cert reached its expiration date.
- ran ipactl start --ignore-service-failures
 Â Â Â Â Â Â a. most services started, obviously pki-tomcatd did not 3) ran "kinit admin"  Â Â Â Â Â Â a. was forced to change the password, but otherwise nothing happened 4) Ran "ipa config-show |grep -i master  Â Â Â Â Â a. I see that the IPA CA renewal master is a different idm machine. 5) Ran "getcert list | grep -E "Request|certificate:|expires:"  Â Â Â Â Â a.I see all certs are currently valid (none expired) 6) Ran the command "getcert list" on the problem server, but I cannot paste the output here because it's on an airgaped environment so while I apologize for this and realize it makes things more difficult, perhaps if you tell me what I should be looking for or more specifically what you're interested in I can pluck that out and manually include it here? So in summary, it is indeed an expired "Server-Cert cert-pki-ca' certificate on the problem server, and it can theoretically be renew by the Master at this time.
The interesting part is the list of expired certs on the failing node (is the RA cert /var/lib/ipa/ra-agent.pem expired?).

You should check that this one is not expired with: # certutil -L -d /etc/pki/pki-tomcat/alias -n 'Server-Cert cert-pki-ca' | grep 'Not '
If the certificate is indeed expired, it will have to be renewed but you need first to find which IPA server is the CA renewal master. On your server, force a service start and check the CA renewal master: # ipactl start --ignore-service-failures # kinit admin # ipa config-show | grep "renewal master"  Â Â IPA CA renewal master: server.domain.com
You need to make sure that all the certificates are valid on the CA renewal master: (on the CA renewal master)# getcert list | grep -E "Request|certificate:|expires:"
- if the CA renewal master is not OK, please post the output of "#
getcert list" (without the grep) on the CA renewal master. This node will have to be repaired first.
- if the CA renewal master is OK, please post the output of "# getcert
list" (also without the grep) on the failing node.
We'll be able to help based on this information. flo
