Hyrax - User Identification (Authentication)

Overview

This document is intended to help those that have been asked to deploy Hyrax into an environment where authentication of users is required. In many such cases Hyrax will be integrated into an existing instance of the Apache Web server (httpd) where authentication services are already configured and in use. In other cases people will be setting up a standalone instance of Tomcat and will be needing to configure it to use one of the supported authentication services. This document means to address both situations.

Terms

Authentication

This is the process of confirming the identity of the user. The end result is a User ID (uid or UID) which may be accessed by the software components via (both?) the Apache API (mod_*) and the Java ServletAPI (Tomcat servlets) used to trigger authorization policy chains or may be logged along with relevant request information.

Identity Provider (IdP)

Also known as an Identity Assertion Provider an Identity Provider (IdP) is a service that provides authentication and identity information services. An IdP is a kind of provider that creates, maintains, and manages identity information for principals and provides principal authentication to other service providers within a federation, such as with web browser profiles.

Service Provider (SP)

A Service Provider (SP) is a Web Service that utilizes an IdP service to determine the identity of it's users. Or more broadly, a role donned by a system entity where the system entity provides services to principals or other system entities.

With respect to this document Hyrax/Tomcat, and Hyrax/Tomcat/Apache each become part of an SP through the installation and configuration of software components such as mod_shib (shibboleth) .
