I know this has been talked about before but I cannot find information that is helping me. I have read the sites/manuals about freeradius but must be missing something, probably simple. I am trying to use freeradius for MAC authentication and see in the logs that the MAC address is coming through as the "calling-station-id" but it's not matching up on the checkval portion of things and I am not sure why. Here are the 2 entries that make me believe the data is coming through correctly: rlm_checkval: Item Name: Calling-Station-Id, Value: 00-26-bb-11-b9-9c rlm_checkval: Could not find attribute named Calling-Station-Id in check pairs but it's not finding the attribute. I wasn't sure if I need to edit the attributes and if so, how do I determine what to put and where do I put it? My other idea was this-is there a way to watch what the radius returns in terms of attributes....I am hoping there is just a definition or something somewhere that I need to change for the calling-station-id. Any help would be greatly appreciated! Steve
