802.1x authentication client sends username as PC-NAME\USERNAME

Hi Team,

I've enabled 802.1x authentication in windows 7 desktop whose PC name is INDIA-ACP with users "radius" as administrator.

When I connect my LAN cable to my authenticator device, the user "radius" is sending his credentials along with pc-name instead just only the username.

Example, in the packet capture i've observed the response identity pkt user credentials appeared as "INDIA-ACP\radius" instead just the "radius" as the identity user.

Please help me in re-solving this issue.

Regards,

Anurag
