University of Calgary Identity Federation (SAML 2.0 / OpenID Connect)
The ucalgary.ca single-sign-on identity provider, run as a Microsoft Entra ID tenant. It publishes signed SAML 2.0 federation metadata and an OpenID Connect discovery document, both keyless and machine-readable, and it is what actually answers an SP-initiated login from the university's own services. This is the institution's federation identity on a vendor platform — one of the few genuinely machine-readable surfaces most universities have, and one that is almost never catalogued.
