KDEsuClient is a dialog and can't be run without a KApplication instance, 
meaning you can only run it from within a program, not from the interpreter. 

However, the best I can get it to do within a program is return -1. Even if I 
force PyKDE to pass it valid arguments (by modifying the PyKDE C++ code), the 
KDE C++ kdesu lib 'exec' method (exec_ in Python) won't popup the dialog and 
execute it.

Since every error in the KDEsuClient C++ code returns -1, it's impossible to 
tell which of about 20 different things is causing it to fail (although I'm 
not getting a diagnostic back from KDE which might narrow it down).

The bottom line is that the kdesu module doesn't appear to work at present or 
at least I don't know how to get it to work. The problem appears to on the 
KDE (not PyKDE) side, so it's going to take quite a while to figure out what 
the problem is. The PyKDE/sip machinery all appears to work correctly.

In the meantime, you can try using KPasswordEdit to get the password from the 
user; I'm not sure how to validate the password from Python though. The 
problem would be reading /etc/shadow.

The other alternative is to require the user to be root to start the program, 
in which case you can run kdesu when invoking the program.
