Enabling the Display Public/Private Option check box in the ESP Options section of the Virtual Service modify screen will display a public/private option on the ESP login page. Based on the option the user selected on the login form, the Session Timeout value is set to the value specified for either public or private in the Manage SSO domain screen. If the user is on a public or shared computer, they should use the default option (This is a public or shared computer), which does not save their credentials locally.
