Stockholm University Shibboleth Identity Provider (SAML2 Metadata)
Stockholm University operates its own Shibboleth Identity Provider and publishes its SAML 2.0 entity metadata anonymously on its registrable domain. The document declares entityID https://idp.it.su.se/idp/shibboleth, an IDPSSODescriptor supporting urn:oasis:names:tc:SAML:2.0:protocol, and shibmd:Scope "su.se". The same entityID appears in the SWAMID IdP metadata aggregate published by SUNET, which makes SU machine-discoverable as an identity provider to every eduGAIN-federated service. This is the one surface in this profile that is unambiguously institution-operated engineering. It is a metadata document, not a REST API — there is no OpenAPI for it and none has been invented.
