SSO from OpenSSO to ADFS via WS-Federation

Not too many blog entries lately, as I’ve been elbow-deep in code - Friday saw the first ever single sign-on from OpenSSO to Microsoft Active Directory Federation Services (ADFS) via WS-Federation (click on the screenshot for a closer look at the output of the ADFS test app). This is OpenSSO acting as an account partner (in ADFS terminology), or identity provider, to ADFS as a resource partner, or service provider. There is a lot of work still to do - single logout, account and attribute mapping, etc, but the core SSO protocol support is all there now.
