We are currently using publicly signed certificates for our eduroam access on a cluster of 2 ClearPass servers.
We are in a situation where one of our certs will be expiring in October of this year, while the other is good until June of next year. The certificate are issued through InCommon, and when I renewed our expiring certificate, I noticed that it is showing that is has a root of Sectigo, where it was previously Comodo. The certificate that is not expiring has a root CA of Comodo. This leads me to the following questions: 1. Is it advisable to run certificates with different Root CAs on different members of our ClearPass cluster? Would we expect to see client issues? 2. If it's not a problem to do this, can I simply add the Root CA for Sectigo to our eduroam CAT configuration, or is there only one Root CA allowed? Any other advice is appreciated. I understand that most institutions are moving to privately issued certificates in order to get control of these certificate chain issues, but we haven't quite gotten there yet. Our plan to properly onboard clients is to use an SSID with a captive portal to direct them to the eduroam CAT download.
