Nanjing University Unified Identity Authentication (CAS SSO)

NJU's central single sign-on, a CAS deployment supporting password, verification-code, biometric and QR-code login. It is not a developer API and there is no public service registration — a relying application must be registered by NJU IT — but the ticket validation endpoints do speak the CAS protocol to anonymous callers and return application/xml, which makes this a real machine-readable institution-operated surface rather than the login page the June 2026 profile recorded.
