We have some very basic integration with HP's connection manager on their ThinPro devices. That integration is supposed to read values out of the device's registry and convert those to arguments to tlclient. However that doesn't work (at least not on the current version of ThinPro). Not sure what's going on as I'm seeing the values just fine running mclient manually, but the wrapper script running as the same user just gets the default values.
User error. You have to run "mclient commit" to actually have the settings take effect.
