I am thinking to setup a wireless network (Cisco Airespace controller 4100) using EAP-PEAP for authentication. We have a Microsoft 2003 server running IAS. My understanding is that a server side certificate is needed at the MS IAS server. I don't know enough about PKI. My question is if I have to use certificate issued by public PKI companies? or, I can enable the Microsoft Certificate services and issue a self-signed certificate for the IAS?
does my question make sense?
