Data Source connection fails

My IADemo and another that I created will not connect. I do have one working data source. I am getting an error about my usernames, but I only have two root and jbecklund and neither will work. Everything seems to be the same for all of them yet only one will connect, I am attaching a scrnshot of the error. Thanks so much!

The “Using password:NO” indicates that there isn’t a password being used in the dataSource.

In the Gateway Configuration Page click on DataSources->Connections. Click the Edit icon next to the datasource. Type in your password in both boxes and check the change password checkbox. Scroll to the bottom and click the Submit Changes button.
