With its factory settings, the device authenticates users based on the local user management. However, as the size of a network increases, it becomes more difficult to keep the login data of the users consistent across the devices.
RADIUS (Remote Authentication Dial-In User Service) allows you to manage the users at a central location in the network. A RADIUS server performs the following tasks here:
Authentication
The authentication server authenticates the users when the RADIUS client at the access point forwards the users’ login data to the server.
Authorization
The authentication server authorizes logged in users for selected services by assigning various parameters for the relevant end device to the RADIUS client at the access point.
The device forwards the users’ login data to the primary authentication server. The authentication server decides whether the login data is valid and transfers the user’s authorizations to the device.
