# UAB Single Sign-On — SAML 2.0 Identity Provider

**Canonical:** https://apis.io/apis/uab/sso-saml-idp/  
**Provider:** Autonomous University of Barcelona — https://apis.io/providers/uab/  
**Base URL:** https://sso.uab.cat/cas/idp/metadata  
**Documentation:** https://sso.uab.cat/

UAB Single Sign-On — SAML 2.0 Identity Provider is one of 11 APIs that [Autonomous University of Barcelona](https://apis.io/providers/uab/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Federation, SAML, Shibboleth, Single Sign-On, and Apereo CAS. The published artifact set on APIs.io includes authentication docs.

UAB self-publishes a complete SAML 2.0 IdP EntityDescriptor at https://sso.uab.cat/cas/idp/metadata (HTTP 200, text/xml), entityID https://sso.uab.cat/cas/idp, shibmd:Scope sso.uab.cat. It declares separate signing and encryption key descriptors and four SSO bindings — HTTP-POST, HTTP-POST-SimpleSign, HTTP-Redirect and SOAP (ECP) — plus HTTP-POST and HTTP-Redirect single logout. This is the single most complete machine-readable contract in this profile and, unlike the equivalent surface at most institutions in this cohort, it is served from the institution's own infrastructure rather than a managed identity vendor's.
