[Zope] Programmatically logging out a user

Hello, How do I programmatically log out a user from Zope ? I've asked this question before, but was told to : 1. Redirect the user to a page that always raises Unauthenticated. See manage_zmi_logout. 2. from AccessControl.SecurityManagement import noSecurityManager noSecurityManager() Are there any other ways out there ? Regards, Danny
