We had a consultant set up our wireless infrastruction a couple of years ago and for the most part I was hands off (big mistake). He did a great job setting it up, but I got zero knowledge transfer.
We authenticate laptop users using machine certificates with a Microsoft CA and Cisco ACS 4.2 server. I can't for the life of me figure out how/where he configured the ACS to specifically look for the certificate and check the CA for it being valid. Any ideas where this is done in the ACS server?
The reason I ask is that we are considering rolling out wired 802.1x and purchasing a new ACS appliance (5.2). I want to make sure I have a firm grasp on the setup before I move forward though.
