Hi I use freeradius 1.1.7 (PLD Linux distribution). In default configuration freeradius work OK but I have problem checking Calling-Station-Id - for check mac adres client validation. My user file contains: "Waldi" User-Password == "12345", It's working. It also works when I add ip verification: "Waldi" User-Password == "12345", Client-IP-Address == "192.168.1.10" But after adding mac verification always got Access-Reject "Waldi" User-Password == "12345", Client-IP-Address == "192.168.1.10", Calling-Station-Id == "xxxxxxxxxxxx" xxxxxxxxxxxx - client mac adress. For test I use NTRadPing Test Utility 1.5. In radiusd.conf: checkval { item-name = Calling-Station-Id check-name = Calling-Station-Id data-type = string notfound-reject = yes } What is wrong or what did I forgot about?
