I have a certificate called AddTrustExternalCARoot.crt that I would like to have FreeRadius start using. I know I need to change the eap.conf to look at the new cert however I was noticing that when the test certificates are created there is both a server.crt and server.pem. Is there a difference and do I need to do something to create a AddTrustExternalCARoot.pem file. Thanks, Joseph R.
