Hello everyone! I am quite new to freeradius and apologize if this has been answered before, I have searched - and a lot of it without finding a good answer. Please direct me if this is already answered. I have a setup of Extreme Wing wi-fi controller and want to implement a guest-user system with captive-portal and device registration/recognition in combination with the standard pre-defined users. I have a radius server going and everything is good as long as I have a user created in radius. Now my challenge is that for "device registration" I see in radius debugs a username sent in form of device mac-address (password is empty) and the expected access-reject as this user is not defined. How can I on the fly add non-existing users into radius database (we use mysql) and from there let accounting take over for session limitations etc? Preferably this would also match some sort of criteria, example a specific subnet. I greatly appreciate any help!
