2897427 - Fiori: Web Dynpro or WebGUI applications open as different user from user logged onto Fiori Launchpad

When opening WebGUI or Web Dynpro applications from the Fiori Launchpad, the app is opened with a different user account than used on the Fiori Launchpad, and may result in an authorization error.

• This primarily will happen in scenarios where a user logs on to the Fiori Launchpad using a user other than their domain account.
  For scenarios with shared browsers, please also see KBA 2463509 - Sessions of Web Dynpro or SAP GUI for HTML applications are not deleted after user is logged off from Fiori Launchpad
