In the general case, no. By default, a subprocess will have the same security context as its parent. The exception is where the parent (the Python processing invoking subprocess.call in this example) is already impersonating a different user; in that case, the subprocess will inherit its grandparent's context. But unless you're doing something very deliberate here then I doubt if that's biting you. Can I ask: are you absolutely certain that the processes you're calling are doing what you think they are and failing where you think they're failing?
