The Authenticate User Server Behavior allows you to set values from the user table into session variables.

What I've seen is that the default is 24 minutes, and this is set within the php.ini file for your server and can be changed via PHP code if the php.ini file is not locked down by a system admin.
$garbage_timeout = 2700; // 2700 seconds = 45 minutes
But again, this may be locked down.
