Just to verify, on the current 3 code that we are on, using the internal db, only one user can use the username/password at a time? With the newer code 5/6, multiple users can use the same username/password? All through Captive Portal of course.
Any device can attach to the network with a valid username and password. There is an option in 5.x and above to not allow users to login with a username that already exists in the user table.
