I have setup RDS 2012 R2 in my private Infrastructure as Remotapp and have published Microsoft Application successfully.

I would like to use the applications that are published on my RDS website with my Mac users as I do with my Windows 7 users (this works no problems)

In my test scenario I am able to connect with my Mac to my internal network from the public side with no issues using Checkpoint VPN and then with my RSA key.

I am able to browse to my RDS site with my Mac using any type of browser. But as soon as I try to connect to an application that I have Published through RemoteApp in RDS on my website I receive a "No such node (ChallengeTypeKey)" error message. I am able to use Remote Resources and the applications get published within Microsoft Remote Desktop (ver 8.0.15) dashboard and am able to use any of them with no issues.

I would rather like to use the same way that I use for my Windows 7 users as I do my Mac users.

How can I resolve this issue?

Update

Apple now has an update to Microsoft Remote Desktop 8.0.16. We are now back to the issue we had with 8.0.5. I get the invalid credentials prompt.

I am recommending using Remoteapp as Remote Resources instead of using the Remoteapp site and connecting to the application.
