The university's institutional identity plane. Tenant 4ffa3bc4-ecfc-48c0-9080-f5e43ff90e5f, whose OpenID Connect discovery document is public and complete at login.microsoftonline.com/reading.ac.uk/v2.0/.well-known/openid-configuration (verified 2026-09-01). The realm lookup returns NameSpaceType "Managed" and FederationBrandName "University of Reading", so there is no on-premises federation server behind it. Probing timetable.reading.ac.uk and myid.reading.ac.uk each redirected into this tenant, which is how its scope was confirmed. The endpoint is Microsoft's; the tenant, its applications and its users are Reading's. No self-service application registration is available to outside developers.
