Overview

  The following sections explain the Fedora 4 AuthNZ AuthN/Z framework, and provide instructions for configuring some out-of-the-box access controls.

...

• Authentication answers the question "who is the person, and how do I verify that they are who they say they are?"  Fedora 4 relies on the web servlet container to answer this question.
• Authorization answers the question, "does this person have permission to do what they want to do?".  Fedora 4 provides three different ways to answer this question:
  • Simple servlet container authentication.  Anyone who has authenticated through the web application container (Tomcat, Jetty, WebSphere, etc.) has permission to do everything – in effect all, authenticated users are superusers.
  • Basic Access Roles authorizations.  Authenticated users are mapped onto one or more preconfigured roles;  a user's role determines what they have permission to do.
  • XACML authorizations.  Policies created using the XACML framework are used to determine what operations are permissible to whom, using user and object resource properties exposed to the XACML engine.
