What is the impact of using the "Include in every user group" option in a RADIUS configuration?

When you select the "Include in every user group" option in a RADIUS configuration, the primary impact is that the RADIUS server is automatically included as a part of all configured user groups on the FortiGate device. This means that authentication requests sent to the RADIUS server can be handled for any user belonging to any user group on the FortiGate firewall, facilitating a unified approach to user management.

This capability is particularly beneficial in environments where multiple user groups exist, as it reduces the need to manually add the RADIUS server to each group individually. It streamlines the configuration process, ensuring that all users, regardless of their group, can be authenticated via the RADIUS server without additional configuration overhead.

Other options provided do not accurately describe the functionality tied to the "Include in every user group" setting. For instance, while securing RADIUS communication and enhancing logging capabilities are important aspects of network security and management, they do not stem directly from this specific configuration option. Similarly, restricting user access based on network zones is a separate functionality concerned with defining access control policies rather than user group inclusion.
