I have installed a scale-out deployment of the GP2013 Web Client using Tenant Services.  I am able to log into the Web Client using an admin AD login and everything works correctly.  But I get the following error when I try to log in as a user (with an AD account that is in the Web Client User group):

ERROR from Session Central Server:
