subprocess and win32security.ImpersonateLoggedOnUser

[Emin.shopper Martinian.shopper]

Dear Experts,

I am having some issues with the subprocess module and how it
interacts with win32security.ImpersonateLoggedOnUser. Specifically, I
use the latter to change users but the new user does not seem to be
properly inherited when I spawn further subprocesses.

I am doing something like

    import win32security, win32con
    handle = win32security.LogonUser(
        user,domain,password,win32con.LOGON32_LOGON_INTERACTIVE,
        win32con.LOGON32_PROVIDER_DEFAULT)

    win32security.ImpersonateLoggedOnUser(handle)

Then spawning subprocesses but the subprocesses cannot read the same
UNC paths that that the parent could.

Any advice on either spawning subprocesses which inherit parent user
properly or changing users in a better way on Windows would be greatly
appreciated.

Thanks,
-Emin
