Windows XP supplicant limitation ?

[Jérémy Cluzel]

Hi,

I want to use
- EAP-TLS for machine auth (with cert.)
then
- EAP-PEAP for the user auth (with login/password)
I managed to make both to work alone but not together...
I just want to follow the xp supplicant behaviour:
- computer auth. before logon to gain network access to the domain 
controler.
- user auth after the doain controler has accepted logon.
Does anybody know if the windows XP supplicant is able to do this ?
Do I need a better supplicant ? aegis? secureW2? Funk Odissey ?

Thanks

Jeremy
