Hello,

 Thank you. It works with XP and FreeEADIUS using EAP/MD5.
We found the problem from "EAP's id". Supplicant(Windows XP) is
disturbed by EAP's id.
AP -> XP             EAP/Request identity (id=1)
XP -> AP -> FR   EAP/Response identity/RADIUS Access  Request (id=1)
and FR RADIUS/challenge (id also is 1), XP is confused and sends
EAP/Reponse identity again. The AP's vendor has fixed it by changing
initial EAP/Request identity EAP id to 0. :p
But it works fine with XP and Win2k RADIUS.

 Sigh...
Although EAP/MD5 is insecure, it's convenient to use for general users.

Because dynamic generation of WEP keys needed in some vendors' AP
 is not supported in FR, I can't use EAP/TLS. :~~
 (EAP module doesnot send "MS-MPPE.." with the Access-Accept packet)
 Any good news about dynamic generation of WEP keys ? :)

 Thank you very much.


 Sincerely,
