Test the Settings of the RADIUS Integration
After entering configuration settings for a security provider, test the configuration at the bottom of the security provider's edit page.
Username and Password
Enter a username and password for an account that exists on the server you are testing. This account must match the criteria for login specified in the configuration above.
Try to obtain user attributes and group memberships if the credentials are accepted
If this option is checked, your successful credential test will also attempt to check user attributes and group lookup.
For these features to be successfully tested they must be supported and configured in your security provider.
If your server is properly configured and you have entered a valid test username and password, you will receive a success message. Otherwise, you will see an error message and a log that will help in debugging the problem.
If the test username and password properly bind to any of the servers, you will receive a success message, even if the other servers are improperly configured. You will receive an error message only if you are unable to bind to any of the clustered servers.
