Seoul National University SAML 2.0 Identity Provider is one of 5 APIs that [Seoul National University](https://apis.io/providers/snu/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include SAML, Identity Federation, Shibboleth, eduGAIN, and KAFE. The published artifact set on APIs.io includes authentication docs.

SNU's federated identity provider, entityID https://kafegw.snu.ac.kr/idp/simplesamlphp, registered by the Korea Access Federation (registrationAuthority http://kafe.kreonet.net, registrationInstant 2024-06-25) and exported into eduGAIN, where exactly one of 10,566 entities carries the snu.ac.kr scope. SimpleSAMLphp, SAML 2.0, SSO and SLO over HTTP-Redirect and HTTP-POST, transient NameID, separate signing and encryption certificates issued to CN=kafegw.snu.ac.kr, O=SNU, OU=Information Systems and Technology, valid to 2028-06-03. Declares shibmd:Scope snu.ac.kr, supports REFEDS Research & Scholarship, and asserts Sirtfi with a published security contact. Institution-operated by definition and machine-readable by definition — and not previously catalogued. Note that SNU does not serve its own metadata: the entityID URL 404s and the SimpleSAMLphp metadata path returns 500, so the eduGAIN aggregate is the only retrievable copy, mirrored here.
