RADIUS Authentication for Access Server VPN Users
Access Server supports Remote Authentication Dial-In User Service (RADIUS) as an authentication method.
You can configure it directly in the Admin Web UI. Sign in to your Admin Web UI and click Authentication > Settings. Alternatively, you can configure this from the command line by changing the configuration key, auth.module.type.
RADIUS authentication overview
Remote Authentication Dial-In User Service (RADIUS) is another protocol used for directory service authentication. You can use RADIUS to integrate Access Server with directory services such as Active Directory, Okta, and open-source programs.
RADIUS requires configuration in the Admin Web UI before it can be used to authenticate users. These settings include which server to contact and any required shared secret code to access the authentication backend.
Once configured, Access Server checks the RADIUS server to validate credentials when a user connects to the VPN.
