The runtime started by AcuConnect on the server takes on whatever environment that the AcuConnect daemon itself was started in when it was started on the server. For example if you log on as root and start AcuConnect, AcuConnect will inherit root's environment. If you log on as userX and then start AcuConnect by issuing the super user account, AcuConnect will inherit userX's environment.
The important thing to note is that the CALLed program does not inherit the client environment of the CALLing program.
