Internet2 and Microsoft to Extend Shibboleth for Windows CardSpace

The Internet2 consortium will develop new extensions to Shibboleth to support Microsoft's Windows CardSpace and other compatible identity selectors.

Shibboleth, a SAML-based software suite, provides Web Single Sign On (SSO) capability and a secure attribute exchange framework to enable individual access to an unlimited number of online resource providers. Shibboleth leverages an institution's existing sign-on and directory system to authenticate users and then passes only relevant identity information to the provider. The system removes the need for universities to set up multiple passwords and accounts for each online resource.

Adding information card support to Shibboleth would enable interoperability with Windows CardSpace which provides critical support for secure user-centric authentication and identity information exchange for web-based applications.
