ENPC SAML 2.0 Identity Provider Metadata
The one machine-readable contract École des Ponts ParisTech operates on its own infrastructure. A live SAML 2.0 EntityDescriptor served as application/xml from idp.enpc.fr, declaring SingleSignOnService over HTTP-Redirect, HTTP-POST and HTTP-Artifact, SingleLogoutService over SOAP, HTTP-Redirect and HTTP-POST, an ArtifactResolutionService and an AttributeAuthorityDescriptor. OrganizationName reads "École des Ponts ParisTech" and OrganizationURL https://www.enpc.fr. The entityID https://idp.enpc.fr/saml/metadata appears in the RENATER Fédération Éducation-Recherche main IdP aggregate, so federation membership is confirmed from the federation's own metadata rather than from an institutional claim. Software is LemonLDAP::NG, not Shibboleth. This authenticates people into federated services; it is not a developer-accessible API.
