I can't be sure without looking at the specifics for that COM api, but many COM
objects return values through "out" parameters--passed by reference.  (This is
because COM uses return values to indicate errors.)  Since Python doesn't
support the usual notion of passing by reference, the PythonCOM implementation
translates "out" parameters into return values (and error returns into
exceptions).  Therefore, (presuming that oNewFolder is indeed an "out" param),
this final line should be written as:

oNewFolder = oRepo.CreateFolder('testfolder', \
                                 'folderdesc', 0, 'Administrators')

Hope that helps...
