My Cisco ACS is not allowing me to log in using the auth-proxy http page. It states: unknown username. When I debug AAA Tacacs I get this information:

The line that interests me is:

5d23h: %AAA/AUTHOR/TAC+: (3914281355): no username in request

Could this be my problem?? Could not be sending the username I entered?? Anybody ever seen this message before?

Thanks
