can the require user's permission be set in a gpo?

Solution 1:

Q: "Can it be set in Group Policy?". A: "Yes it can."

Go to Computer Configuration>Policies>Administrative Templates>Windows Components>Remote Desktop Services>Remote Desktop Session Host>Connections

Specifically the Set rules for remote control of Remote Desktop Services user sessions and change it to Enabled and set the option to Full Control with User's Permission

EDIT:

You can also se it under User Configuration. If you set it under Computer Configuration it will apply to all users logging onto the server where that GPO is applied. If you set it under User Configuration it will apply to all users that the GPO applies to. If you set it under both Computer Configuration and User Configuration then the Computer Configuration setting takes precedence.

Thanks to TheCleaner for the assist in adding the additional detail for the actual setting.
