[Zope] what permissions are required for [un]restrictedTraverse?

what permissions are required for [un]restrictedTraverse? I recently added the call to 'restrictedTraverse()' in a method and I can't get permission to use it except when I'm logged in as superuser. I need to be able to let other users use this method. How do I do that? Thanks, Jason __________________________________________________ Do You Yahoo!? Get Yahoo!
