Cannot remote to Mac when ARD "Curtain Mode" is enabled

Hi,
I will assign this to one of our dev. Thank you

Hi xexen,

I've looked at your issue but unfortunately, so far, I wasn't able to produce it.
I just wanted to make sure I was using the same steps you are.

I first connect to a Mac using the official ARD client.
I then click the toolbar to active curtain mode and enter a lock message
While the screen is locked, I use RDM to connect to the same machine.

The connection is successful and I can see and control the remote desktop.
Does this match your setup?

After further review, it seems like the Apple Remote Desktop machine I was connecting to has a problem with the Apple Remote Desktop Server which locks automatically on disconnect. So I tested connecting to another system. If you enable "curtain mode" using ARD then disconnect. Curtain mode disables automatically. If you stay connected using ARD in "Curtain Mode", and try connect using Remote Desktop Manager you are denied connection. Remotix and ARD behaves the same way. So it seems the issue is actually with the ARD server I was trying to connect to.

Glad to hear this issue wasn't caused by our client.
If anything comes up again, please let us know.
