Microsoft is to announce the “release to the Web (RTW) of Active Directory Federation Services 2.0 on May 5 “ADFS 2.0, codenamed “Geneva,” is part of Microsoft’s identity/security platform, as well as of its Azure cloud operating environment. ADFS, a Windows Server component, provides Web single-sign-on (SSO) technologies to authenticate a user to multiple Web applications. The ADFS 2.0 technology is part of the Azure Services layer, company officials have said, given ADFS is designed to allow users to employ single sign-on across both cloud-hosted and on-premises applications. Microsoft's testing during the event focused on SAML's Service Provider Lite, Identity Provider Lite and eGovernment profiles. The ‘”lite” versions of those are a significant sub-set of the full profiles. Microsoft says it plans to support other SAML profiles based on demand. In addition, ADFS 2.0 is part of a larger identity platform that includes the Windows Identity Foundation (WIF) and Windows Cardspace,” revealed John Fontana.
