Shibboleth

Shibboleth is an Internet2 project, part of their middleware activities.

Shibboleth has been chosen as the architecture to use for the NZ Access Federation.

Key concepts of Shibboleth are:

  • Federated administration
  • Access control based on attributes
  • Privacy management
  • A framework for multiple, scalable trust and policy sets (federations)
  • A standard (yet extensible) attribute value vocabulary

The original Internet2 Shibboleth documentation links to installation and configuration guides on the Shibboleth Wiki. However, for deployment of Shibboleth within the NZ federation, follow the NZ specific deployment information for Identity Providers and Service Providers.
