WS-Federation remains essential for enterprise identity management despite being legacy technology, particularly in healthcare and finance sectors with older SharePoint and ADFS systems. The protocol uses passive federation through browser-based redirects, exchanging XML metadata between Identity Providers and Relying Parties. Key implementation steps include configuring metadata URLs, setting up relying party trusts, mapping claims to specific schema URLs, and testing endpoints. Common production issues involve certificate expiration, clock skew between servers, and signature validation failures. Identity brokering tools can bridge WS-Fed legacy systems with modern OIDC protocols, reducing integration costs by approximately 30%.
