[Zope] permission, roles, security question

Hi, I'm working on the following problem: A user is authenticated in a user folder and has the following roles: Anonymous (can, should a authenticated user have the role anon ?) Authenticated, Manager, some others In the permission of 'View' I will do the following: permission not acquired permission for Anonymous is disabled permission for Authenticated is not vissible (is that correct ?) permission for Manager, some others are enabled Will the 'View' permission enabled or disableed on the affecting roles ? Anonymous disables the 'View' permission (or does it mean Anonymous doesn't enables 'View' permission ?) Manager enables the 'View' permission. Regards, Dirk
