[Zope] Login and user security

I'd like to setup a user security environment similiar to that used on the Zope site. Users can signup, and login to access personal pages and logout when done. However, I'm a bit confused about things. Perhaps I don't understand enough of the underlying security model. Additionally, the how-to, FAQ and other docs are difficult to follow. Has anyone published a sample like this? Or, perhaps, has the Digital Creation people can provide the source to the DTML pages and methods? Any pointers would be fantastic.
