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 methods section.
Click Test button.
Enter Radius password to the Password field.
Click Next. You will see a message Authenticator "Radius Client" passed the test.
