WAYFs and Discovery
Of course, the real reason I was in Windermere was not to photograph ducks but to present some slides on the discovery problem in Shibboleth. You can download a copy of the presentation “WAYFs and Discovery” here (1.4MB PDF).
The abstract (accidentally omitted from the meeting material) was:
The standard model of Identity Provider discovery in Shibboleth deployments is that of a federation-supplied, central discovery service called a WAYF. Although an essential backstop, this approach has significant shortcomings. We present some recent work in the area of multi-federation WAYFs, and review alternative discovery technologies (both present and future) that allow deployers to improve the user experience.
