Auto-login to Outsystems Apps with desktop credentials

I'd like my users to be auto-logged into my Outsystems application using their Windows login, since that matches their login in our Users app.  I've been experimenting with the Login action in the System eSpace, but can't seem to get it to work. 

Has anyone been able to do this successfully that would share their process?
Have you tried turning "Integrated Authentication" on in the Users eSpace management?
That seems to have worked (the first link you provided).  Thank you very much.  Not sure I'd have found that on my own.
