We are in the process of implementing Tableau as a hosted solution with SAML authentication with a company called Helio Campus. The engineer assigned to work with us set up our environment in a way that when we go to the URL assigned to that service, we get automatically redirected to the IdP authentication page instead of a standard main page with a login button/link.
I contacted the engineer about it stating that most of our hosted solutions had an initial page, and the guy got furious. The fellow pretty much rubbed in my face in an arrogant and ignorant way I didn't know anything about Tableau. He was the expert and knew what he was doing. I knew nothing! There was no way to have a front-end page like that with a hosted/SAML integration. He pretty much refused to talk about it.
Do any of you guys with a hosted environment have your system set up like that? In a way that you cannot have a main page users go to and from there get to the authentication page?
