Restrictions on Authentication
Interstage Single Sign-on provides some functions to prevent illegal access. The functions include the
function for requesting re-authentication after a specified time elapses, the function setting a user
validity period and the lockout function for disabling password input after several times consecutive
invalid password input.
Re-authentication and Re-authentication Interval
A re-authentication interval can be set, so that an authenticated user is requested to be authenticated
again after a specified time elapses from the first authentication. This function reduces the risk of
unauthorized use of the user's client computer by a third person even when the user leaves the client
computer without closing the browser after the user has been authenticated.
