Add Federated Identity Provider use case for AI Agents - #5217
Conversation
📝 WalkthroughWalkthroughThis change adds documentation for federated identity provider authorization. It describes attribute-to-access mapping, seeded access, external policy decisions, and access constraints. It also adds links from the AI Agents and B2C documentation and registers the page in the sidebar. ChangesFederated Identity Documentation
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to This PR adds federated authorization guidance for users and AI agents, including optional external policy decisions. It is not merge-ready until the broken navigation links and required page structure are corrected and the guidance clearly defines which component makes and enforces authorization decisions, including safe behavior when external policy or identity data changes or is unavailable.

documentation to distinguish local-role authorization from external PDP mode:
state that ProductName owns access decisions when authorization is local, while
an external policy decision point supplies the decision in delegated mode and
ProductName enforces the result. Keep the surrounding identity-authority
statement unchanged.

Qualify the authority statement for external PDP mode.
The page says <ProductName /> is authoritative for access, but later says it can delegate the decision to an external policy decision point. In delegated mode, the external PDP supplies the policy decision and <ProductName /> enforces the result. Distinguish local-role authorization from delegated authorization.
Based on the supplied PR objective and AuthZEN flow, this page must distinguish the external PDP decision from <ProductName /> enforcement.

Purpose
Authorizing a user or agent managed by a federated identity provider has no coverage in the Agent ID use-case section. The six existing problems in Solve It assume ThunderID already knows who the delegating principal is; this adds the use case for when it does not.
Approach
Added as a fifth branch card on the Agent ID index page and a standalone sidebar entry, alongside Understand It / Solve It / Try It / Design Decisions, rather than as a numbered seventh problem inside the existing six-problem journey. That sequence is tightly cross-referenced (a numbered table, three postures, a "Where to Start" ordering, and Design Decisions building explicitly on it), and inserting into it would mean renumbering and rewriting cross-references throughout, which felt like a bigger and riskier change than this PR should make. The new page cross-links into the existing journey (
solve-index,solve-acts-for-user) and out toIdentity Sources and Datain the B2C section, which gets a short paragraph pointing back.Covers: attribute-based role/group mapping, access seeded at onboarding, consistent authorization across sign-in/token-exchange/identity-assertion entry points, authorization with no local record, and delegating the decision to an external AuthZEN policy decision point.
