 Application Bridging for Federated Access Beyond Web (ABFAB) Use Cases

Abstract

   Federated identity is typically associated with web-based services at
   present, but there is growing interest in its application in non-web-
   based contexts.  The goal of this memo is to document a selection of
   the wide variety of these contexts whose user experience could be
   improved through the use of technologies based on the Application
   Bridging for Federated Access Beyond web (ABFAB) architecture and
   specifications.

1.  Introduction

   Federated identity facilitates the controlled sharing of information
   about people (a.k.a. "principals"), commonly across organizational
   boundaries.  This avoids redundant registration of principals who
   operate in and across multiple domains, both reducing the
   administrative overhead for the organizations involved and improving
   the usability of systems for the principal.  Simultaneously, it can
   also help address privacy-related concerns, along with the regulatory
   and statutory requirements of some jurisdictions.

   The information that is passed between organizations may include
   authentication state and identity information that can be used for
   many purposes, including making access management decisions.  A
   number of mechanisms support the transmission of this information for
   web-based scenarios in particular (e.g., the Security Assertion
