[Zope3-Users] Comflicting security annotations

[FB]

Hi,

what is Zope supposed to do, when there are conflicting security annotations
applied to an object?

I'd like to make an object inaccessible - except for members of a given role.
This is how it should look like:

  grantPermissionToRole('zope.View','role.admins',Allow)
  denyPermissionToRole('zope.View','zope.Anybody',Deny)

Is this possible? If not, why? Maybe there's a more elegant solution?
'zope.Anybody' is defined as a "group" in etc/principals.zcml. Can I
use it like a role?

Is there a role, any anonymous user *and* any authenticated user is
automagically assigned to?

Thank you for any help.

Regards,

Frank
