Shibboleth Identity Provider (SAML 2.0)
Zhejiang University operates a Shibboleth SAML 2.0 Identity Provider, entityID https://idp.zju.edu.cn/idp/shibboleth, registered in CARSI (the CERNET Authentication and Resource Sharing Infrastructure) and interfederated through eduGAIN since 2020-01-31. It advertises SingleSignOn, SingleLogout, ArtifactResolution and AttributeQuery endpoints across SAML 1.0, SAML 1.1, SAML 2.0 and the Shibboleth-native binding. Caveat recorded honestly: the metadata served at the entityID is the unmodified Shibboleth installer artifact — validUntil 2020-01-29, expired for six years, with no Organization or ContactPerson block and the template placeholders still commented in. Federated consumers work from the CARSI/eduGAIN aggregate, not from this endpoint.
