RSASecurid and PEAP

Hi i would like to know if this thing (scenario) is possible... 1) i want to authorize/authenticate a user with a couple username/OTPpassword (RSASecurid) through a Freeradius server (i proxy the acces-request to a RSARadius-Securid server). It's ok. 2) (then, if i get an Access-Accept) (in a post-proxy section?) i want to initiate an EAP Challenge between my XP-Wireless-supplicant client and FREERADIUS (not the RSA radius)... Can i configure something like that authorize { ... suffix ... } post-proxy { (if access-accept...) eap } Hope this mail is not too obfuscated...and then is able to be decoded... Regards Paul
