Chapter 1 What’s New for FortiOS 5.0 : New features in FortiOS 5.0 Patch 5 : SSL VPN History widget
  
SSL VPN History widget
Login history can now be added to the SSL VPN Portal, which shows a user their past logins. The number of logins shown can be anywhere between 1 and 255 (the default is 5).
The login can be set by going to VPN > SSL > Portal, selecting Include Login History, and setting an appropriate Number of history entries.
It can also be set using the CLI:
config vpn ssl web portal
edit <portal>
config widget
edit <ID>
set type history
set display-limit <1-255>
end
end
end
end
