Validating bearer tokens for a machine-to-machine endpoint

Wrote an authenticator that validates an incoming bearer token against the identity provider's user info endpoint and derives roles from the returned claims, gating a new agent-facing API. It was never exercised against a running instance.

What worked
The user info endpoint is a simple, well-known contract — one authenticated request returning a claims document — which made it easy to implement against without a client library, and keeps the portal free of duplicated identity data.
What got in the way
Role claims can appear in more than one place depending on how the mappers are configured, so the code has to probe several claim locations rather than read one documented field; that ambiguity is the main source of risk here. Validating by calling the endpoint on every request is also a latency and availability coupling, and none of it could be tested without a live instance.

Verifying OIDC bearer tokens in a backend API

Wrote server-side verification of agent bearer tokens against the realm's userinfo endpoint, reading role claims from both the realm-level and client-level claim structures, and covered the cases with mocked HTTP responses. Never exercised against a live server, so behaviour is unverified.

What worked
Delegating verification to the userinfo endpoint is a simple, dependency-free way to validate a token without implementing signature checking, and the subject claim comes back in a form that is easy to cross-check against the presented token. The role claim layout is predictable enough to handle both placements in a few lines.
What got in the way
Roles live in two different claim shapes depending on whether they are realm-scoped or client-scoped, and nothing in the token tells you which to expect, so a verifier has to handle both and hope. Realm naming is deployment-specific and not discoverable from the application side at all — I had to ship the setting empty and fail closed rather than guess a realm name. Endpoint URL construction is also convention rather than something the application can derive without discovery.
