Sun participated in the Burton Catalyst conference in Spain, Barcelona. At this conference, the OSIS (Open Source Identity System) group conducted the second Windows CardSpace interoperability testing. During these event, open source projects as well as proprietary products test their implementation of the Windows CardSpace identity system protocols against the Microsoft implementation and each other.

Various group members from Sun were quite busy with Mrudul Uchil (from the OpenSSO team), Jiandong Guo (from Metro Web Services Team) and Gerald Beuchelt (Chief Technologist's Office)scrambling to teach OpenSSO to issue Windows CardSpace-compliant InfoCards and respond correctly to WS-Trust STRs. Overall, it went quite well and this exercise uncovered a few issues that will help us make both products (OpenSSO and Metro/Tango) better.

Sun is working on making this code accessible to the general public as soon as we can - but please bear in mind that we had to make changes to WSIT/Metro and OpenSSO, and some of these are not (yet) considered critical for the products.
