McMaster University Shibboleth Identity Provider is one of 8 APIs that [McMaster University](https://apis.io/providers/mcmaster/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Federation, Shibboleth, SAML, eduGAIN, and Canadian Access Federation. The published artifact set on APIs.io includes authentication docs.

McMaster's own SAML 2.0 Identity Provider, the authentication authority behind MacID. Publishes machine-readable SAML metadata anonymously at its entityID, carrying an IDPSSODescriptor, an AttributeAuthorityDescriptor, a UIInfo display name and description, and the scope mcmaster.ca that bounds every scoped attribute the IdP may assert. Registered in the Canadian Access Federation by CANARIE and republished into eduGAIN, with SIRTFI asserted. This is an institution-operated, standards-conformant, machine-readable surface, and it satisfies both the shibboleth and saml domain standards of the Kin Score education regime.
