Our university has three campuses and each campus maintains their own Identify Provider (IDP). To facilitate user authentications, our normal practice is to have an application send them to a SAML Discovery Service and the user selects which campus they are on. This information is sent back to the application which then authenticates using the IDP. Has anyone else done something similar with Tableau Server?
My gut feeling is that Tableau Server won't care if a discovery service is being used so long as the IDP returns a compatible certificate and Tableau Server has the correct metadata file.
