[Zope] Get error about Unauthorized

[Fu-Ming Tsai]

Hello.  I've been through the Zope "Web Application  Construction 
Kit" book tutorial, chapter 5, "Building a Portal and Adding Serices" 
 "Creating a Type with ZClasses".

Each time, when attempting to add the new ZClass object in a user 
folder, this error is generated:

Exception Type Unauthorized 
Exception Value You are not allowed to access 'manage_addProduct' in this 
context 

Does anyone have any sense of what this means and how to fix it?

My Zope is 2.7.4 running on Sci-Linux and python is 2.3.4.

Thanks.

The following is the traceback I got
