I think there is a step we missed when setting up our certificate infrastructure. Do we need to register a certificate for each of our ExtremeControl RADIUS servers (we have 15 total) with our certificate authority (internal active directory domain controller). I know just enough about certificates to be dangerous, but I "think" the client get this message because the server is not "registered" with our CA and therefore the client can't verify the RADIUS servers identity. Just need some guidance on why this is happening and what would stop it. Also, if someone has setup their windows environment to use 802.1x with ExtremeControl servers and EAL-TTLS, please let me know if there is some step-by-step guide out there to follow. Thank you.
