TU Berlin Shibboleth Identity Provider (SAML 2.0 Metadata)
The institution's own Shibboleth Identity Provider, operated by the ZECM and registered in the DFN-AAI federation. Its SAML 2.0 metadata is public and machine-readable — 15,920 bytes of XML declaring entityID https://ephraim.tu-berlin.de/shibboleth, an IDPSSODescriptor with HTTP-Redirect, HTTP-POST, POST-SimpleSign and Shibboleth AuthnRequest SSO bindings, SOAP logout and an AttributeAuthorityDescriptor with SAML1/SAML2 AttributeQuery, all scoped to tu-berlin.de. This is the one machine-readable surface a university operates by definition, and it is entirely TU Berlin's.
