I have a client who has implemented ArcGIS Enterprise 10.6.1 with Active Directory integrated named users. The Web Adaptor with Windows Authentication is placed in front of the Portal to provide automated log-in experience.
Client now wants to use ADFS as SAML compliant identity provider. However, client wants to retain IWA-like user experience that is all domain users logged-in automatically when accessing the Portal. My understanding is with ADFS, users will still need to provide their domain username and password on Enterprise Log-in page. This is not a true Single Sign-On experience rather a Same Sign-On experience. Is there a way to achieve automated log-ins with ADFS? Does it require some configuration at ADFS level?
