Sydney Airport Authentication

docs: null
note: >-
  Sydney Airport publishes no public API and therefore no OpenAPI securitySchemes.
  The only machine-readable authentication contract it publishes is the OpenID
  Connect Discovery 1.0 document for the ForgeRock Access Management realm that
  fronts InfoSYD, its gated airline / ground-handler / on-airport-tenant portal.
  Everything below is derived verbatim from that document (harvested 2026-07-28,
  HTTP 200) plus the authorize request observed on the InfoSYD login redirect.
  It describes how a credentialed partner authenticates - it does not describe any
  callable resource API, because none is published.
