[Zope] Role specific access rights for Python scripts

[Andreas Tille]

Hello,

I try to set up a user role which is allowed to vie the output of some
python scripts in a certain folder.  I created a new role and started
by checking every single checkbox for this role in the "Security"
tab of the new script.  But if I select the URL of the script I
get:

    Zope has encountered an error while publishing this resource.

   Error Type: Unauthorized
   Error Value: You are not allowed to access manage_test in this context

Any hint, what might be wrong here?

Kind regards

         Andreas.
