That's because the factory attribute isn't supported for the
securityPolicy directive. It appears, however, that you can
provide a callable object (i.e. a factory) and it will be called
without arguments.  See

   lib/python/Zope/App/Security/metaConfigure.py

I'd prefer that there be an explicit factory attribute.
Want to add one?
