Problem with MS-CHAPV2 and Windows XP SP3

[Henrique Camolezi Pacheco]

I'm trying to implement 802.1x and LDAP with freeradius, but am having 
problems with the certificate.
When I try to authenticate, I get the following error message:
Sending Access-Challenge of id 66 to 10.10.12.77 port 1825
Reply-Message = "Access-Accept "
