Hi Florence,
Thanks for the feedback, let me clarify the situation on the
certificates:
- External CA is still valid and it is a self-signed certificate
that we use for other services. So we can manually sign any
service certificates to get them back up and running
- IPA CA is expired, let's say Aug/10
- I have managed to import a renewed IPA CA and ran `ipa-cert-fix`
(and also seemed to have run `ipa-certupdate`) on a current date,
let's say Sep/20. But not all services were recovered and now
there is no overlap between earliest date in service certificates
and the original IPA CA
- I have run a backup, but also did some system upgrades to get
the `ipa-cacert-manage prune` command, but when I've tried to
recover it, I've found that the backup was not there.

I suspect we cannot do this all within LDAP right? If we get back the expired certificates, how do we restore them in each service? `httpd` is straightforward, and I guess `nssdb` should be doable, assuming the same key is used, but is there another database type where the certificates are located? Are all the certificates tracked by `getcert list`? Is it safe to assume that after running something like `ipa-cert-fix`, they are using the same private key?
Some symptoms in the current setup:
- When we are forward in time, `pki-tomcatd` is able to run, but
then I can't do any `ipa-cert-fix` or `ipa-cacert-manage renew`.
From what I've read, all of these commands (or at least
`ipa-cacert-manage renew`) must be done backwards in time.
- When we are backwards in time `pki-tomcatd` is unable to run,
failing to access `:8080/ca/admin/ca/getStatus`. This then blocks
various other services to be run. But about `ipactl restart`, only
`pki-tomcatd` service is actually failing (and ipa service itself
of course).
I have navigated to `ou=certificateRepository,ou=ca,o=ipaca` and indeed there are still a bunch of certificates there in linear order. What are the services I should look for in there? I am using Apache Directory Studio and I can download the `userCertificate`. Should I just run `certutil -A` with those values with corresponding `subjectName`?
BTW, I want to document this process on the website, should I
make a PR on the github repo or is there somewhere else?
Kind regards,
Cristian
Hi,

I have tried my luck around with all the helpers: `pki-server cert-fix`, `ipa-cacert-manage`, `ipa-certupdate`, etc. but each one is failing on me for multiple reasons.
- `ipa-cacert-manage` Cannot update the CA with `--external-cert-file` because the root ca is not detected to be in the trust list
This command is useful if you need to trust a new external CA or renew IPA CA. Is your IPA CA expired?
- `ipa-cert-fix` Was run without overlapping validity time, and the certificate were re-created, so now it is not recoverable, neither back in time, nor in current time
It is recommended to do a backup before running ipa-cert-fix. If you didn't, and want to try the back-in-time method, you can still find the original certificates in the LDAP database (below ou=certificateRepository,ou=ca,o=ipaca) but it requires a bit of searching. You would need to restore the expired certificates, go back in time and force the renewal.
- `pki-tomcat` is failing
What is the current situation? Which certs are expired (getcert list)? If you start the services with "ipactl start --ignore-service-failures", is pki-tomcat the only service failing?flo
It is quite a mess and I would like to ask for some guidance on how one could recover manually from such dependency issues:
- Is it possible to do a `ipa-server-install` and keep the user data?
- If I sign all of the service's certificates manually, what are all of the manual steps needed to get the services back up so that the helpers can be run.
- I've tried to install the CA certificate in the nssdb database, ldap, and /etc/ipa/ca.crt. Are there other locations?
- I've recreated an httpd certificate signed by the root, but I can't figure how to do the same with the ones located in the nssdb database, i.e. to recreate a csr with the same data as one of the certificates there
- What is the order of services that should be updated. My understanding is CA -> `certutil`'s CA -> httpd + slapd + pki-tomcat (not sure where the last one is or how to edit it) -> `ipa-certupdate`
