As the name implies, this package aims to provide an enterprise level authentication & authorization service. There are two parts to this package, the service layer which handles A&A requests and a PHP client. Support for other clients (e.g. Java, ASP/VB, etc) is possible further supporting cross-platform enterprise needs. Main features are: 1) Web Service-based 2) implements notion of a Provider which is capable of hitting a specific data store (DBMS, LDAP, etc) 3) Implements a single credential set across a single provider 4) 100% OO-PHP with the client producing a user object that can be serialized to a PHP4 session.
