Only the system and security administrators can congure login activity tracking and view the login activity details
of other users.
If you enable user login statistics, the system displays the last successful login details of the current user and the
details of any failed login attempts by others.
If you use the login statistics time-period days command to set a custom time period, the system
only reports the login statistics during that interval.
