I've done something similar.
First off, if your passwords are stored using irreversible encryption
(e.g. Unix passwd file), you are only going to be able to use
EAP-TTLS/PAP. Reason being that both PEAP and MSCHAPv2 require a
challenge-response type mechanism, where the server has the plaintext
password available to it (either by reversible encryption or plaintext).
For EAP-TTLS, WindowsXP supplicants will either be installed with the
wireless card (in the case of the newer Intel ones) or you'll have to pick
up SecureW2. Both options work quite well.
You don't need client certs with EAP-TTLS.
The MacOS X.2 (or better) with latest patches will do TTLS builtin.
There is a supplicant available for Linux, too -- Xsupplicant, courtesy of
the Open1x project.
Let me know if you need any other tips or tricks.
