A client is running a Tableau Server and a web app, which both handle authentication using AD and Salesforce. They would like to embed the web app into a dashboard so that the web app would not require a user to type in credentials. Do we have a way to configure the Tableau Server so that it would pass the username to an iFrame where the embedded web app runs? This would trigger automatic sign-in, since the user is already signed in to AD or SF.
I think this is more about AD and SF configuration issue to allow sign-in via iFrame, but I want to make sure if there is some configuration options on Tableau Server that I have missed.
I recommend reading through the Tableau Embedded Analytics Playbook: Tableau Embedded Analytics Playbook
It covered different options, you'll need to choose the right one based on your client's Tableau Server and AD configuration, but one of the options there should work for them.
