Description of problem:
OSP10 director set the ironic endpoint to "RegionOne" instead of "regionOne". This caused the UI to display two regions with different services.  If you select the wrong region, you can not browse to admin or project tabs as you are forced back to the login prompt. You need to select the correct region before you can browse away from the Identity tab.
