You can also use Microsoft My Apps to test the application in any mode. When you select the Palantir Foundry tile in the My Apps, if configured in SP mode you would be redirected to the application sign-on page for initiating the login flow and if configured in IDP mode, you should be automatically signed in to the Palantir Foundry for which you set up the SSO.
