Timeout:
After successful verification, an authentication session is established.
Authentication Timeout decides the active time of the session. Within the
active time,
the device keeps the authentication session open with the
associated client.
To reopen the session, the client needs to log in the web
authentication page and enter th
e user name and password again once
authentication timeout is reached.
By default, authentication timeout is one hour. Select Custom from the drop-
down list to customize the parameter.
Redirect:
Disable by default. Redirect specifies that the portal should redirect the newly
authenticated clients to the configured URL.
Redirect URL:
Enter the URL that a newly authenticated client will be directed to.
