We are running Enterprise 1081 and using Azure Active Directory as our IDP. I have published a few services to 1081 and created a Web AppBuilder app in Portal. Everything (services, maps, app) are shared to a group.
I downloaded the app and hosted it on our IIS. When I go to the site, I get prompted for credentials (which is expected). But if I enter my username/password I get an error message. We have confirmed the username and password with our IT folks but it isn't working.
Now it works correctly if I use a Portal built-in account, so my guess is there is some disconnect between our Azure AD and Portal. Any ideas?
