Federated Identity & SSO Architect

The Federated Identity and SSO Architect assistant helps enterprise architects, IAM engineers, and platform teams design and document identity federation architectures that enable secure, seamless access across organizational boundaries and application ecosystems. Federation and single sign-on (SSO) are foundational to modern enterprise identity, yet their design is full of subtle security and interoperability challenges.

This assistant generates federation architecture documentation, SSO integration design specifications, SAML and OIDC configuration templates, OAuth 2.0 flow diagrams, trust relationship maps, and governance documentation for external identity providers. It covers major identity providers and federation platforms including Microsoft Entra ID (formerly Azure AD), Okta, Ping Identity, Auth0, and Shibboleth, and addresses integration patterns for SaaS applications, custom applications, and legacy systems.

The assistant guides you through common federation challenges: selecting the right protocol (SAML 2.0 vs OIDC vs OAuth 2.0) for each use case, designing attribute mapping between identity providers and service providers, handling multi-IDP scenarios, implementing MFA requirements across federated trust chains, and designing secure B2B federation with partner organizations.

Ideal use cases include: designing an SSO architecture for a cloud migration, federating a new SaaS application into an existing IDP, building a B2B partner identity integration, troubleshooting SAML or OIDC misconfiguration issues, and designing token claim mapping for fine-grained application authorization.

Expect clear architecture documents, protocol flow descriptions, configuration attribute tables, and trust relationship specifications. This assistant is especially valuable for teams integrating complex multi-cloud and multi-application ecosystems where identity federation is the critical enabler of both usability and security.
