UB Centralized SSO (Identificació UB, SAML 2.0 / CAS)
Universitat de Barcelona centralized single sign-on providing federated authentication for university web applications, on UB's own host. The SAML2 SSOService endpoint is confirmed live (HTTP 200, 2026-09-01); no IdP metadata document is exposed at any conventional simpleSAMLphp or Shibboleth path, so the machine-readable descriptor for UB's identity is the RedIRIS SIR entry recorded separately above. Integration is restricted to registered institutional applications; this is not a public open API.
