The two documents are the same abstract thing — "how do I talk to your authorization server" — standardized a few years apart, and a client that assumes one well-known path is a safe fallback for the other will be wrong in at least four distinct ways: | Provider | RFC 8414 path | Relationship to the OIDC document | |---|---|---| | Google | HTTP 200 | **Field swap**: drops `scopes_supported`, adds `op_policy_uri`/`op_tos_uri`/`service_documentation` | | GitLab | HTTP 200 | **Strict superset**: identical plus one extra field, `registration_endpoint` | | Okta | HTTP 200 | **Subset-plus-vendor-field**: drops every ID-token/JWKS field, adds `identity_chaining_requested_token_types_supported` | | Red Hat SSO (Keycloak) | HTTP 200 | **Byte-identical** to the OIDC document | | Auth0 | HTTP 200 | **Byte-identical** to the OIDC document | | Microsoft (`common`/`organizations`/`consumers`) | HTTP 404 | **Not implemented** | | Salesforce | HTTP 404 | **Not implemented** | | Apple | HTTP 302 | **Not even a clean miss** — falls through to the public website's generic `/filenotfound` redirect, with tracking cookies set on an unauthenticated discovery probe | No two of the eight behave the same way, and the two "identical" cases (Keycloak-based Red Hat SSO, and Auth0) are the only pair that agree with each other. A client written to try RFC 8414 first and fall back to OIDC discovery — or vice versa — needs to tolerate all four shapes: extra fields it must ignore, missing fields it must not assume exist, a 404 it must treat as "try the other path," and (Apple) a redirect to an unrelated 200/404-shaped HTML page it must not mistake for a discovery document. A second, independent axis compounds this: Microsoft's OIDC issuer is a literal unresolved `{tenantid}` template on its two actually-multi-tenant discovery variants (`common`, `organizations`), not a real issuer string, so RFC 8414 §3's "compare `issuer` byte-for-byte against the token's `iss` claim" validation cannot even be performed from the discovery document alone on those two variants — only `consumers` (a fixed GUID) and a concrete tenant-id URL resolve to a literal issuer.
