Federated identity management, or identity federation, allows enterprises to exchange identity information securely across domains, providing browser-based single sign-on (SSO).
Identity federation also integrates access to applications across distinct business units within a single organization. As organizations grow through acquisitions, or when business units maintain separate user repositories and authentication mechanisms across applications, a federated solution to browser-based SSO is desirable.
This cross-domain, identity-management solution provides numerous benefits, ranging from increased end user satisfaction and enhanced customer relations to reduced cost and greater security and accountability.
