[Zope] ZClass permissions

[Ross Patterson]

Do this:

Make sure your authenticated as a manager, i.e. that you can view the
management pages.  THEN try and view the "Edit" management tab of
your instance and click cancel when it prompts you for authentication.
You'll then get an error page with a traceback in the source for the
page.  The dtml traceback will tell you what method you call in
your dtml is causing the problem.  Then you can try calling that
method directly and you can use that traceback to see where in that
method the problem is.  Then you can look at the source for that
method, go to the line number given in the method traceback, and that
should give you an indication what in your ZClass the method is trying
to access that it can't.  Then you can fix the problem in the Define
Permissions ZClass management tab.

But that would be the precise way that takes longer but yields a
greater understanding.  You could just map permissions to themselves
in the Define Permissions tab one by one until it works.
