Using RADIUS Authentication 9.2
RADIUS (Remote Authentication Dial In User Service) is an industry-standard way to manage logins to
many different types of equipment in one central location. The NetGuardian 216 G4 connects to your
central RADIUS server. Every time a device receives a login attempt (usually a username & password),
it requests an authentication from the RADIUS server. If the username & password combination is found
in the server's database, an affirmative "access granted" reply is sent back to the unit device, allowing
the user to connect.

After successfully entering the settings for the RADIUS server, the NetGuardian Web Browser will
prompt users for both a Username and Password, which will be verified using the information and
access rights stored in the RADIUS database.
RADIUS logons are case-sensitive . If the RADIUS server is unavailable or access is denied, the local
user profiles will work via craft port access only. Also, the "dictionary.dps" files (included on the
Resource Disk) needs to be loaded on the RADIUS server for access-right definition. If RADIUS is
enabled on the NetGuardian, local authentication will be invalid through the web and can only work via
craft port.
