Do not do that. Use the self-signed certificate created during installation.

None of that has anything to do with them signing or encrypting anything, that causes you to sign requests. Unless you need that, don't.

That does not appear to be the SP, or Shibboleth, but their IdP.

You'd have to ask them, it's their software. Unless that location bar is lying, because that's not a Shibboleth SP URL, it looks like a SSO endpoint in an IdP to me.
