TU Delft SAML 2.0 Identity Provider (NetID) is one of 3 APIs that [Delft University of Technology](https://apis.io/providers/tu-delft/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Federation, SAML, SSO, eduGAIN, and SURFconext. The published artifact set on APIs.io includes authentication docs and API documentation.

TU Delft's SimpleSAMLphp identity provider — the machine-readable half of NetID. It publishes a signed SAML 2.0 EntityDescriptor with an IDPSSODescriptor and is registered in SURFconext, the Dutch national research and education identity federation operated by SURF, which in turn publishes into eduGAIN. This is the surface class universities operate by definition and almost never get catalogued for: it is institution-run, machine-readable, and it is what actually lets a researcher at another institution authenticate against a TU Delft service. Note what it is NOT — there is no OpenID Connect discovery document (login.tudelft.nl/.well-known/openid-configuration returns 403) and no OAuth 2.0 authorization server.
