    Thanks a lot. This article really helps. I got into an issue. When trying to access the adfs/ls outside the VM, I am first prompted for credentials. I enter my corp credentials. And then I get 503 error. Service not available.

    Appreciate this. It was exactly the issue. The ADFS App Service credentials were already entered, but re-entering them did the trick. Thanks
