...remember though that working != secure [necessarily]. Clients defaulting 
to accept any radius server cert, or those that default to prompt the user, 
are vulnerable to rogue AP/credential stealing attacks etc. This may be 
acceptable in your environment, but if not, you'll still need to actively 
configure the client.
