I have tried using the verbose-security option in Zope 2.8.6. I cannot see that it is actually doing anything different from the standard security. I have previously used VerboseSecurity and know what the error log should look like. in my zope.conf security-policy-implementation PYTHON verbose-security on I am sure that zope.conf is being read, because if I type in invalid values, I see error messages on startup. I am using Plone 2.1.2. When I access an object that I do not have permission I get the following error message: Time 2006/03/24 12:32:51.623 GMT+1 User Name (User Id) jc (jc) Request URL http://bla.bla/Bla/folder_listing Exception Type Unauthorized Exception Value Not authorized to access binding: context Traceback... I somehow expected a little more. I expected to be told what permissions I needed, and what permissions I had. Can anyone tell me if I am doing anything wrong?
