Force the client to use one specific EAP method

As Matthew suggested, I've removed the configurations for the others EAP methods, indeed now they don't work anymore. But, as Matthew already said, the clients will always choose whatever method they want to use or in the most cases the chosen method is the one set on the supplicant configuration file. I thought of making a script that would change the 802.1x configuration of the supplicant, but then every client should download and run the script, which is no practical at all. So, any other workaround that you're aware of? I was wondering if adding a realm could help somehow. Luca
