GUF Basic Information
GenericUserFolder
The GenericUserFolder is a roll-your-own user folder. It provides hooks for you to list users, authenticate a user, list a users roles etc. It supports cookie based authentication to allow you to create a nifty login screen to your site. It provides an alternative when existing Zope user authentication methods need to be mixed and matched, or arn't configurable enough, or don't quite do what you want. If you need to write your own authentication mechanism or query inhouse datasources, it will be much easier writing code to plug into GUF rather than writing a acl_users folder implementation and associated baggage from scratch.
This software requires a basic knowledge of basic Zope security (see the Zope Content Managers Guide) and non-trivial DTML scripting ability.
