Hello !

I am just trying this:

Process p = new Process();
ProcessStartInfo psi = new ProcessStartInfo();
SecureString password = ReadPassword();
psi.UserName = args[0];
psi.FileName = args[1];
psi.UseShellExecute = false;
psi.Password = password;
.....

This works naturally on Linux too - but the required user is NOT the
executing user of that process - it is the same as the starter.

This looks like a bug in the mono classlib/runtime. It is not
a professional solution to run it via a "shell'ed" sudo.
What workarounds are availabe to solve this problem ?

Su/sudo is actually the one and only "professional" approach
under Unix/Linux.

Any other way will eventually end up in reinventing su/sudo, which
is pretty hard (security wise) to be implemented.

For a desktop application you may want to look at kdesu/kdesudo (KDE), gksu/gksudo (GNOME), beesu (Red Hat). For a console app: su/sudo.
