This Zope product defines a fully-pluggable user folder, intended for use in all sites
PluggableAuthService is a highly extensible replacement user folder for
Zope 2. It can manage arbitrary user, group, role, and property
definitions with ease, and works best in very heterogeneous environments
(users stored in MySQL, groups in LDAP, properties from the filesystem, etc).
For authentication, it supports HTTP Basic Auth, Cookie Auth, Domain Auth,
and can be extended to support just about any other mechanism.
