The RADIUS Client authentication method forwards your authentication request to a third-party RADIUS Server.
This authenticator enrolls automatically and it's not possible to remove it.
By default a user name from your corporate directory is used. To change it specify a required name in the User name field. Then click Save button.
To test the enrolled authenticator follow the steps below:
Click the RADIUS Client icon in the Enrolled authenticators section.
Click Test button.
Specify RADIUS password in Password.
Click Next. You will see a message Authenticator "RADIUS Client" passed the test.
