How to Use the RADIUS Server Wizard with Nagios XI

Nagios XI can integrate with a Remote Authentication Dial-In User Service (RADIUS) server to provide authentication, authorization, and accounting (AAA). With RADIUS enabled, users authenticate against a credential database, typically verifying their username and password in a directory. The RADIUS server then responds by granting or rejecting access based on the verification.
