Authentication

Traditional authentication uses a name and a fixed password and generally takes place when the user first logs in to a machine or requests a service. RADIUS relies on an authentication database to store user IDs, passwords, and other information.

For user authentication, the server can use a local database, UNIX passwords or LDAP. Database location is configured in the server's /etc/radius/radiusd.conf file during setup, or by updating the file through SMIT. See RADIUS configuration files for more information on RADIUS configuration files.
