Two open-source identity management projects say they have achieved a key milestone in the development of identity services that connect products regardless of maker or platform. The integration, which has been under development for more than a year, will be on display next week at the RSA Conference in San Francisco. The technology on display at RSA will also be more “user-centric,” by virtue of integration with Microsofts CardSpace. The vendors involved in the integration are working to realize a vision of seamless identity layers that can be accessed from systems running on Apple OS, Microsoft Windows or Linux.”]
