We're in the process of decomissioning our oldest IPA servers (built in 2014). We've migrated the roles successfully and are making sure everything is ready to switch over to the new set, and just wanted to check a few observations/inconsistencies.

* On some of our newer clients /etc/ipa/ca.crt contains the root and the server certificate of the enrolment server instead of just the root - did the behaviour  of ipa-client-install change at some point?

Hi,
I just want to make sure we are using the same terminology. When you refer to the root certificate, do you mean that IPA was installed with an externally signed CA? If that's the case, it's expected that /etc/ipa/ca.crt contains both the external CA and IPA CA.
Or are you referring to IPA CA?
 
* Our root contains the OCSP URI of one of the servers to be decomissioned in the Authority Information Access field. My understanding is that a client would never do an OCSP lookup on a root certificate so do we need to re-sign or add a CNAME prior to switching off?

* When enroling a client, ipa-client-install pulls down an expired RA certificate - however /var/lib/ipa/ra-agent.pem on all servers is current. Where might the expired cert be stored? Doesn't appear to cause an issue in any case.
Where do you see this expired RA certificate? Clients do not have any RA certificate, only servers do.
