SAML and federated login
Notes and Web Federated Login is a feature that has been around for a long time, however it has had great improvements in both versions 10 and 11.
In earlier versions of Domino, only two specific IdPs were supported. Starting in Domino V10, Domino supports AuthnRequests for SAML requests, meaning any SAML 2.0 provider that supports AuthnRequests is expected to be compatible.
Starting in V11.0.1, when using Notes Federated Login or Web Federated Login is used to extract the ID file from the ID vault, the value for the ID Vault policy setting Allow automatic ID downloads is now ignored.
