Burton Group's Catalyst Conference North America 2009 will be the host of the single sign-on interoperability demonstration for cloud applications on Wednesday night, July 29th. Instead of requiring a password for every off-premise application, this demo will illustrate how standards such as SAML, WS-Federation, OpenID, and others can be utilized. Participants in the demo will represent a broad range of technology providers, SaaS application providers, Internet properties, and social software sites. Several hosted or SaaS application participants include SalesForce.com, Google Apps, eXpresso Corp, WebEx, more to come.

Interop participants have agreed upon the base scenario for the demo. In this case, identity provider instances will demonstrate single sign-on to several application environments - using SAML, WS-Federation and OpenID. Where supported, identity providers will also demonstrate just in time provisioning of user access. There will be an advanced scenario that combines SAML 2.0 and OpenID to meet NIST's Level 1 through Level 3 identity assurance guidelines. This scenario is being built around a sample application, led by JanRain.
