VU Amsterdam SAML 2.0 identity provider (SURFconext / eduGAIN)
Vrije Universiteit Amsterdam operates its own SAML 2.0 identity provider on Microsoft ADFS and publishes signed, machine-readable federation metadata for it. entityID http://stsfed.login.vu.nl/adfs/services/trust; SingleSignOnService at https://stsfed.login.vu.nl/adfs/ls/; the metadata document carries both IDPSSODescriptor and SPSSODescriptor roles and supports SAML 2.0 alongside WS-Federation and WS-Trust. The same entity appears in the SURFconext national IdP feed with mdui:DisplayName "Vrije Universiteit Amsterdam" and shibmd:Scope vu.nl, from where SURFconext publishes it onward to eduGAIN. This is the surface a university operates by definition, it is genuinely first-party, and it was entirely absent from the June 2026 profile of this institution.
