Documentation at https://www.npmjs.com/package/@node-saml/passport-saml suggests to use npm install passport-saml instead of npm install @node-saml/passport-saml because this pull request's content is not present at latest version pushed to npmjs ( https://www.npmjs.com/package/@node-saml/passport-saml/v/4.0.0-beta.1 )
