HKBU Identity Federation (Shibboleth IdP / SAML 2.0 metadata) is one of 5 APIs that [Hong Kong Baptist University](https://apis.io/providers/hong-kong-baptist-university/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Federation, Shibboleth, SAML, and eduGAIN.

HKBU's own SAML 2.0 identity provider, entityID https://buidp01.hkbu.edu.hk/idp/shibboleth, registered in eduGAIN by the Hong Kong Access Federation (HKAF) since 2018-03-14 with scope hkbu.edu.hk. The metadata document is served anonymously (HTTP 200, application/xml, 12,306 bytes) and declares both an IDPSSODescriptor and an AttributeAuthorityDescriptor across nine endpoints — SAML 2.0 HTTP-POST, HTTP-POST-SimpleSign, HTTP-Redirect and SOAP artifact/attribute bindings, plus SAML 1.1 and the legacy Shibboleth 1.0 AuthnRequest profile — and single logout. This is the one machine-readable interface HKBU both authors and operates end to end; the signing keys and the attribute release are HKBU's. It is not an HTTP API and carries no OpenAPI.
