What is the main function of the command diagnose debug authd fsso list?

The command "diagnose debug authd fsso list" is primarily used for troubleshooting user authentication, specifically in the context of Fortinet's FSSO (Fortinet Single Sign-On) feature. When executed, this command provides a live view of the FSSO user list, showing which users are currently authenticated and their associated attributes. This is essential for troubleshooting authentication issues, helping administrators verify that users have been recognized and authenticated properly by the firewall.

In scenarios where there are connectivity issues, user access problems, or questions regarding the status of users logged in through the network, this command can provide real-time insight into the FSSO service's activity. Recognizing which users appear in this list can assist in diagnosing permission issues or confirming that the credentials supplied are functioning as expected.

The other options presented do not align with the command's specific function. The command does not log events for all users, nor does it provide statistics about overall firewall performance, and it does not analyze firewall settings against security protocols. Thus, its focused role in troubleshooting user authentication makes the choice clear.
