Unable to connect to the active user session when you launch a remote control session on a Mac OS X Lion 10.7 managed device

Source: ZENworks 11; ZENworks Configuration Management; Remote Management.
Explanation: When you launch a remote control session on a Mac OS X 10.7 managed device, you are not connected to the active user session. Instead, you are prompted for the login credentials in the default login screen.
Possible Cause: The default OEM VNC server in Mac OS X 10.7 supports several remote control sessions in parallel (similar to Windows terminal sessions), so support for connecting to the active user session on a Mac OS X 10.7 managed device is discontinued.
Action: To launch a remote control session on the Mac OS X 10.7 managed device and to connect to the active user session without sharing the login credentials:

  1. Disable the default screen sharing option on the Mac OS X 10.7 managed device:

    1. Click System Preferences icon.

    2. Select the Sharing preferences.

    3. Uncheck Screen Sharing checkbox within the Service list.

  2. Download and install Vine Server 4.0 (currently in beta) from the Vine VNC TestPlant.

  3. Set the VNC password in the System Preferences tab of the Vine Server window.

  4. Run Vine Server 4.0.

    NOTE:Launching of remote control session on a Mac OS X 10.7 managed device with Vine Server installed has not been fully tested and is not supported.
