I have a mixture of wireless clients in this customer environment such as PDA, Cisco clients and third party PCMCIA cards.
Customer requires me to propose an EAP authentication method to authenticate them. WHat suits them?
I plan to have authentication done on application level. Could you recommend any?
It will more be a matter of what all the clients support, you normally set it up for the least supported client or have different VLANs with different security levels based on what you clients support
LEAP is only on Cisco or CCX certified cards
If you base OS is Windows XP and the client cards they have support EAP then EAP-TLS is a pretty good choice if they will support PEAP then that is even better again.
So to make this choice you really need to know exactly what client cards you have and what they support The AP will support all of them so the choice is based on the clients
