Affiliation-based Federation with...ABBA?
By docteger on Jul 03, 2008
An affiliation (referenced by an
affiliationID) is a grouping of entity providers configured using OpenSSO and maintained by an affiliation owner who chooses the members without regard to the boundaries of any circles of trust which might also include the entity providers as members. Affiliation-based federation is indicated by a boolean flag at the service provider and uses the
affiliationIDdefined for the remote provider (since a local provider can participate in more than one affiliation). If enabled, the authentication request will be sent with the affiliation flag set to
true. Affiliation data is part of the provider metadata. A service provider request denotes whether the request is being made as part of an affiliation or not. If services are invoked as an affiliation member, a service provider might issue an authentication request for a user on behalf of the affiliation. When authentication is secured, the user can achieve single sign-on with all members of the affiliation. And for those who don't know - I have an affiliation with ABBA. In honor of the upcoming release of Mamma Mia here's the group's music video for the title tune (mysteriously aped in Muriel's Wedding for Muriel and Rhonda's karaoke performance of...Waterloo?). And here's the trailer for the film. Meryl Streep (sounding great), Julie Walters and an uncredited (?) Christine Baranski - what a trio!!
