UdeM Shibboleth Identity Provider (SAML metadata)
Université de Montréal's campus single sign-on, published as machine-readable SAML 2.0 entity metadata. The document declares an IDPSSODescriptor supporting SAML 2.0, SAML 1.1 and the legacy urn:mace:shibboleth:1.0 AuthnRequest profile, an AttributeAuthorityDescriptor for out-of-band attribute queries, SSO and SLO endpoints over HTTP-POST, HTTP-POST-SimpleSign, HTTP-Redirect and SOAP, artifact resolution on port 8443, and mdui display names in French and English. This is not an API a developer calls; it is the contract a relying party consumes to federate with UdeM, and it is machine-readable, versioned by publication, and permanently public.
