On the Details pane, navigate to the Permissions tab. Click the Add button.
The Add Permission to User dialog displays. Enter desktopuser in the Search textbox, and click Go. Select the check box of the user to be assigned the permissions. Scroll through the Assign role to user list and select UserRole.
