[Zope] Session Timeout?

Hi, I'm using sessions in 2.5.X but get not session timout. In the session_data object the value "Data object timeout value in minutes" is set to 20. But after 20 minutes of inactivity I can access the resource though. Only closing the Browser invalidates a session. What I is as follows: 1. Trying to get a session 2. If no session is available the user is forced to enter name and password. 3. If name and password are correct a new session is created for this user.
