[Zope] User profile management product

[Benjamin Buffereau]

Hi there,

I need to manage user profiles, where "user" can stand either for an anonymous
visitor or for an identified visitor. In other words, I need a session tracking
product that:
-allows the visitor to become a member, log in, log out, etc.
-allows to store and retrieve visitor profiles.

CoreSessionTracking can't do that, and I don't need a complete content
management framework, as all I want to manage is user profiles. Anyone knows a
product matching my needs?

Thanks,
Benjamin.
