USTC Shibboleth Identity Provider (跨校资源认证中心) is one of 6 APIs that [University of Science and Technology of China](https://apis.io/providers/ustc/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Federation, SAML, Shibboleth, eduGAIN, and CARSI. The published artifact set on APIs.io includes API documentation.

USTC's self-hosted Shibboleth IdP 5.2.2, publishing a 15KB SAML 2.0 EntityDescriptor for entityID https://idp.ustc.edu.cn/idp/shibboleth with a shibmd:Scope of ustc.edu.cn, SSO and SLO endpoints across Redirect, POST and POST-SimpleSign bindings, SOAP artifact resolution and attribute query on port 8443, and twelve certificates. It federates into CARSI, the Chinese Academy of Sciences CSTCloud AAI and eduGAIN, which is how USTC members reach licensed library databases from off campus without a VPN. Institution-operated by definition and confirmed by address ownership — this is not a managed federation platform wearing a university hostname. Anonymously readable; the metadata is archived in this repository.
