The University of Hong Kong's own Shibboleth SAML 2.0 identity provider, entityID https://hkafidp.hku.hk/idp/shibboleth, scope hku.hk. It self-publishes signed metadata (HTTP 200, application/xml, 14,831 bytes) declaring SAML 1.1 and SAML 2.0 SSO, single logout, artifact resolution and attribute query endpoints, transient NameIDs, and the eduPerson and SCHAC attributes it releases. Registered by the Hong Kong Access Federation (JUCC) on 2016-12-15 and exported to eduGAIN, carrying the REFEDS Research and Scholarship entity category and SIRTFI assurance certification. This is HKU's most substantial institution-operated machine-readable surface and the one no catalog had recorded.
