[Zope] permission, roles, security question

[Dirk Datzert]

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
