Kyoto University Shibboleth Identity Provider (GakuNin) is one of 4 APIs that [Kyoto University](https://apis.io/providers/kyoto/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Federation, Shibboleth, SAML, SSO, and GakuNin. The published artifact set on APIs.io includes API documentation and authentication docs.

Kyoto University operates its own Shibboleth SAML 2.0 identity provider, run by the Institute for Information Management and Communication, with public machine-readable metadata at the canonical /idp/shibboleth location. The EntityDescriptor declares entityID https://authidp1.iimc.kyoto-u.ac.jp/idp/shibboleth, a shibmd:Scope of kyoto-u.ac.jp, and single sign-on over SAML 2.0 HTTP-POST, HTTP-Redirect and the legacy Shibboleth 1.0 profile. The IdP is a registered member of GakuNin, the Japanese academic access management federation operated by the National Institute of Informatics and an eduGAIN participant; the federation aggregate also carries Kyoto's supercomputer service provider, entityID https://web.kudpc.kyoto-u.ac.jp/shibboleth-sp, for the Academic Center for Computing and Media Studies. University accounts are SPS-ID (faculty and staff) and ECS-ID (students), with multi-factor authentication. Service-provider connections require committee approval: this is institutional SSO infrastructure, not a self-service API.
