To recreate "the Response has an InResponseTo attribute" error in the QB logs by leaving QuickBuild at the login page for +40 seconds
without logging in and then attempting to use SSO to log in.
Also sometimes get the error if I sign out of QuickBuild and then try to log back in quickly, but for the most part sign out/wait 40 seconds/try to log in seems to break it every time.

When it fails, the client then gets an error like this and is not logged into QB:
Message: invalid_response
The Response has an InResponseTo attribute: ONELOGIN_ea35ba25-0bcf-458f-b3fa-1e92574af60a while no InResponseTo was expected

Root cause:

com.pmease.quickbuild.QuickbuildException: invalid_response

If you click "Back to Dashboard" and try to log in again (within 40 seconds), it works fine and you are able to stay connected/logged into QB just fine. FYI - I was able to create this issue in QB10 as well as QB11.
