Microsoft Tuesday laid out the roadmap for its identity management platform, including federation services that will ship next year and eventually provide Web single sign-on features.San Diego - Microsoft\u00a0this week\u00a0laid out the roadmap for its identity management platform, including\u00a0federation\u00a0services that will ship next year and eventually provide Web single sign-on features.Microsoft plans to announce the roadmap and the renamed federation service during the second-day keynote at Microsoft\u2019s annual TechEd conference Tuesday morning.Formerly codenamed TrustBridge, the technology is now called Active Directory Federation Service (ADFS), Microsoft said. It will ship next year as part of the Windows Server 2003 Update, codenamed R2, and allow users to federate identities between corporate boundaries.Federation\u00a0lets an identity credential issued by one company be used for access to a partner\u2019s network.\u201cADFS will be one of the biggest splashes in the identity management space we make this year,\u201d says Levon Esibov, group program manager for directory and identity services.ADFS will become the cornerstone of Microsoft\u2019s adoption of Web services security protocols on the Windows platform, supporting authentication and authorization services between disparate systems and across corporate boundaries.ADFS will eventually provide the Web single sign-on capabilities that Microsoft\u2019s identity platform currently lacks. Those capabilities are now provided by third-party partners including Netegrity, Oblix and Open Network. Before Microsoft can claim single sign-on capabilities, however, support for Web services protocols, such as the Security Assertion Markup Language (SAML), must be prevalent across vendors\u2019 identity products.ADFS will support\u00a0WS-Security, an OASIS standard, as well as protocols Microsoft is developing along with its partners such as WS-Trust, WS-Policy, WS-Secure Conversation, WS-Federation, WS-Authorization and WS-Privacy.On Monday, Microsoft unveiled its Web Services Enhancements 2.0, a package for developers that includes those same protocols.Microsoft\u2019s work on federation protocols is in competition with work being done by the Liberty Alliance, which is using SAML as the foundation for a federated identity framework. Microsoft officials say they plan to eventually interoperate with the Liberty specifications.The ADFS enhancements are the leading edge of a series of incremental upgrades to Microsoft\u2019s identity management platform, which revolves around Active Directory, Active Directory Application Mode and Microsoft Identity Integration Server (MIIS).The roadmap includes the next version of MIIS, which will ship next year. MIIS 3.5 includes a feature called \u201cdeclarative provisioning,\u201d which will eliminate the need to write provisioning scripts, user self-service features, and audit reporting. It also will establish the server as an application platform.The biggest change is that MIIS 3.5 for the first time will eliminate the requirement that users deploy the server with the aid of consultants.Before the 3.5 release, Microsoft will ship Service Pack 1 for MIIS later this year. It will include a set of new management agents for connecting to identity and other data stores. Today, MIIS has some 20 connectors. The service pack will add password synchronization capabilities, a management agent SDK for building custom agents and will incorporate workflow and approval features.The identity roadmap also stretches to Longhorn server, which is slated to ship in 2007. Microsoft will add manageability enhancements to Active Directory and a digital ID service called Identity System, which will provide users with a portable identity that can be used with consumer and Web services.
