Hi everybody!! I'm trying to do a web based authentication and a MAC auth with the same NAS, so I plan to take the data in the table raddacct (calingstationid) in the first login of each user, to create a new user in the radcheck table for the MAC auth in the next sessions of the same user. Example. User1 -> web based auth -> radacct data -> callingstationid (MAC) taking callingstationid -> radcheck username I made it manually and it works, but I have an issue. The CallingStationID is written in this way: 90-4E-2B-61-BF-E3 But, the MAC auth request is arriving in this way: 904e2b61bfe3 So If I copy the callingstationid from raddacct table, to the radcheck table, the MAC auth won't work; because the formats of data are differents. How can I modify the calling station ID that will be written in the radacct table? I have read that there are some ulang lines in the policy.conf file, but I don't understand how to use them.
