Should you use passwords, X.509, Kerberos, LDAP, SAML or something else? Do you know the challenge that your developers are faced with when looking at identity technologies, no one of which works for all scenarios. In this session, learn how a new abstraction layer for identity - the claims based identity model - gives developers a single way to secure an application regardless of type of app (web app, web service or other) or scenario (B2B, B2C, B2E, enterprise, cloud). Find out how, using this model, it is easy to enable security features previously out of reach: supporting multiple authentication types in a single application, enforcing "step up" to a stronger authentication type on the fly and delegating user identity between applications. Learn how to use this model in .Net with Microsoft "Geneva", how it works with Active Directory using Microsoft "Geneva", how it works with Windows CardSpace, and how it interoperates across platforms.
