If you install the Dashboard on the same server as the Core Services computer, users can launch the Dashboard from the Web console without having to re-enter their Dashboard credentials.
If the Dashboard resides on a separate computer from Core Services, update the Dashboard settings in the Web console to support single sign-on: Go to Your_ID > Settings > Dashboard.
For more information, see Considerations for Installing the Dashboard and Enabling Users to Launch the Dashboard
in the Help for the Web console.
