Ok, I think you may be mixing up Service Provider (SP) and Identity Provider (IdP).
On the SAML SP page you configure ClearPass as Service Provider; where users use their Entra ID account to sign into ClearPass services like Policy Manager, Guest, Guest Operator, etc:

On the SAML IdP page, you configure ClearPass to be the Identity Provider, so there users are authenticated on ClearPass to use another (SAML SP) service.
For the SAML SP Certificate, in case you want to use ClearPass as the SP, you can create your own (server) certificate. May be self-signed, or you can sign it from another CA or even the Onboard CA, as it's something you would import in your IdP (Entra), so it doesn't need to be a public trusted certificate.

Subject: Do we have any Documentation for Entra and Clearpass SSO?
Hi Herman
Thanks for the doco.
We were trying to create a web login with Entra SSO
When I try importing the Entra based Certificate (Base 64) to SAML Idp Configuration:
I cannot import the certificate generated by Entra
As it gives me an error as ClearPass wants a Private Key but Entra doesn't have Private Key in certs.
Do you have any idea
Regards,
