Hello! I am struggling with a mac-auth-bypass problem with my Cisco 6509s and my FreeRADIUS server.  The 6509 sends the radius server the request, FreeRADIUS authenticates it as OK, but yet my port remains in the "authfail" state on the switch.  Does anyone have any ideas?  Here is my debug output from the radius box: The first part is the debug output / freeradius startup, the 2nd part is a request I get from my switch to authenticate some "azbycx" user, so I just added it to users for now, and then the 3rd part is the request/response for my MAC address to be authenticated. Thanks for your help!
