Authenticate with FreeRadius + MySQL + PEAP

[tiodacio]

Hi,

I'm using FreeRADIUS Version 1.1.6 for Freebsd 6.2 to authenticate Wi-Fi clients. Im using WPA2. My users are in a MySQL database and i'm using EAP-PEAP and mschapv2 for authentication.

When i create a user "test", for example, in the radcheck table and configure this user in a Windows XP the authentication proceeds without problem, but when i create a user "test at some.domain.com" in radcheck and configure this user in Windows XP client, the authentication fails.

In my proxy.conf i have two entries, the realm NULL and the realm some.domain.com, both authenticating locally, and the realm some.domain.com with the nostrip option. In my radiusd.conf, i'm using realm suffix with @ as delimiter.

The strange is that with the same configuration, the user "test" was authenticate correctly but the user "test at some.domain.com" was not. Any suggestions?

Follow my configuration options:
