Shibboleth and InCommon: An Update and Implications Ken Klingenstein Project Manager Internet2 Middleware Initiative Chief Technologist University of Colorado, Boulder Steve Olshansky Internet2 Middleware Initiative Shibboleth, an inter-institutional approach to resource sharing, has made steady progress since its first conceptual presentation at CNI almost four years ago, and is now in rapidly widening deployment. Even as the base product continues to add important functionality, the graphic user interfaces for librarians, system administrators, and end-users are beginning to emerge. Moreover, InCommon, the federated trust mechanism that builds on Shibboleth to enable real production use, is now beginning operations. The Shibboleth architecture is also being adapted for use in other applications of interest to the CNI community, including P2P file sharing, instant messaging, and Grids. This briefing will provide an update on the status of Shibboleth, other marketplace factors, InCommon, and the advent of new applications.
