[Zope] User Class

Greetings. I'm a bit of a Zope and Python newbie, so please forgive me if I get some of the lingo wrong. I would like to build a user class in python where I can store information like "First Name", "Last Name" etc. I would also like to store the userid and password in the instances of this class, and authenticate against them. It seems as though I should inherit from the Zope user class, but I'm not sure exactly how to go about doing that. Thanks so much in advance! Keith R. Alperin
