Imperial Shibboleth Identity Provider (SAML 2.0)

Imperial's own Shibboleth IdP, and the one unambiguously institution-operated machine-readable contract it publishes. The metadata document at /idp/shibboleth is a live 12.5KB SAML 2.0 EntityDescriptor with entityID https://shibboleth.imperial.ac.uk/shibboleth, one IDPSSODescriptor and one AttributeAuthorityDescriptor, SSO and SLO endpoints for the SAML2 Redirect, POST and POST-SimpleSign bindings plus legacy Shibboleth SSO, SOAP ArtifactResolution and AttributeQuery on :8443, and a `shibmd:Scope` of imperial.ac.uk. The entityID is registered in the UK Access Management Federation aggregate. This is not a REST API and is not self-service — consuming it means being a federation member — but it is a published, versioned, machine-readable interface contract that Imperial itself operates.
