Using a known root CA for RADIUS authentication isn't really recommended.
Why?
P.S. just to clarify, it's not "using a known root CA for RADIUS authentication", rather it's using a server cert signed by a known root CA.
Sure. It's because *anyone* can set up an AP, and a RADIUS server that your PC will accept. If the AP has the same SSID as (say) your work, it will happily send your work username && login via EAP to the rogue AP. The various EAP methods *should* have tied usernames (i.e. domains) to a field in the certificate. e.g. a cert with CN "radius@example.com" should be sent logins for "user@example.com", but NEVER sent logins for "user@example.net" You should ONLY send your login credentials when you *know* who it is on the other end of the EAP conversation.
