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

Question

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

Hi Anurag,
According to your description, the user name changed from radius to INDIA-ACP\radius. Due to the packet was send from the Windows 7 PC to the authenticator device, it seems that the problem is in Windows 7 PC. Have we used INDIA-ACP\radius as the username
and chose “Remember my credentials” before? When we choose “Remember my credentials”, the credentials would be saved and managed by Credentials Manager in Windows 7. Windows credentials management is the process by which the operating system receives the credentials
from the service or user and secures that information for future presentation to the authenticating target. Maybe the credentials was saved by the Credentials Manager, when we connect the authenticator device, the Credentials Manager send the saved credentials
to the authenticator device. To verify if the credential was saved in the Credentials Manager, please open Credentials Manager in the control panel.
