Trinity Microsoft Entra ID tenant (OIDC + SAML metadata) is one of 12 APIs that [Trinity College Dublin](https://apis.io/providers/trinity-college-dublin/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Federation, OpenID Connect, SAML, and Entra ID. The published artifact set on APIs.io includes authentication docs.

Trinity's Microsoft Entra ID tenant, d595be8d-b306-45f4-8064-9e5b82fbe52b, resolved from the tcd.ie domain hint. OpenID Connect discovery and SAML federation metadata both answer unauthenticated. Recorded as `federation` rather than discarded as a vendor host: the host and the protocol implementation are Microsoft's, the tenant and the identities in it are Trinity's, and rss.tcd.ie was observed redirecting sign-in here. There is no public client registration and no third-party developer access.
