I have a freeradius server that I am trying to test for Mac Auth with NTRadping tool. When I use radclient on the server itself there is no issue. However when I use NTRadping from a PC the server appears not to receive the Calling-Station-Id. If I remove the authorized_macs part I can use NTRadping (meaning using simply a user/password combination it works, but I want to use Mac Auth). Below the debug info from freeradius -X Note that the info says "invalid user" although that user is perfectly valid and as i said the system works for this user when i simply remove the authorize_macs code in default. Help would be appreciated....
