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
in this example) is already impersonating a different user;
in that case, the subprocess will inherit its grandparent's

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?
