Microsoft Entra ID Tenant — OpenID Connect Discovery
Queen Mary's Microsoft Entra ID tenant, GUID 569df091-b013-40e3-86ee-bd9cb9e25814, EU region scope. The OpenID Connect discovery document resolves from the qmul.ac.uk domain hint, which is what ties the tenant to the institution rather than to a supplier, and the same GUID appears independently in the Entra application-proxy CNAME chain fronting elements.qmul.ac.uk, the university's Symplectic Elements deployment. This is the cloud sign-in plane for institutional applications and the second half of Queen Mary's identity estate alongside Shibboleth. It is not an open API: no external client can register against it.
