GakuNin Shibboleth Identity Provider (SAML 2.0)

Shibboleth / SAML 2.0 Identity Provider for institutional single sign-on, registered in GakuNin, Japan's national academic access management federation operated by NII. Advertises the Shibboleth 1.0 AuthnRequest profile, SAML 2.0 SSO over HTTP-POST and HTTP-Redirect, and SAML 1.0 / 2.0 SOAP AttributeQuery on port 8443. Published SAML metadata inside a national federation aggregate is the most machine-readable interface this institution operates. It is a federated authentication endpoint for institutional login, NOT a public OAuth or OpenID Connect developer API, and must not be counted as one.
