Chulalongkorn University Identity Federation (Microsoft Entra ID tenant) is one of 10 APIs that [Chulalongkorn University](https://apis.io/providers/chulalongkorn/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Federation, SAML, OpenID Connect, and Single Sign-On. The published artifact set on APIs.io includes authentication docs.

The university's cloud identity, and the most complete machine-readable contract anywhere in this profile. Entra tenant 271d5e7b-1350-4b96-ab84-52dbda4cf40c carries the federation brand name "Chulalongkorn University" and is authoritative as a Managed namespace for both chula.ac.th and student.chula.ac.th. Its OpenID Connect discovery document and its signed SAML 2.0 federation metadata both resolve HTTP 200 without credentials. Two negatives were probed rather than assumed: Chulalongkorn has no entity in eduGAIN — a full pull of 10,616 eduGAIN entities returned zero matches — and no Shibboleth identity provider resolves under chula.ac.th.
