Consider an environment that uses 802.1x PEAP authentication via RADIUS. Typically, this is to authenticate wireless clients.
In this environment there are multiple RADIUS servers and clients will be served by whichever is available.
I have seen two approaches with regard to the server certificate presented to clients.
In the first, the same certificate is configured on each RADIUS server. The CN is something generic, e.g. "wireless.mycompany.com"
In the second, the certificate is different on each server and the CN is the hostname of the server, e.g. "server1.mycompany.com"
My question is: Are both acceptable solutions? What are the pros and cons of each approach?
EDIT: Interested particularly in comments relating to ease of roaming for clients.
