Unless you fancy rolling your own, win32security is the way to go. There's the beginnings of an example here:

If you want to live slightly dangerously (!) my in-progress winsys package is designed to do exactly what you're after. You can get an MSI of the dev version here:

http://timgolden.me.uk/python/downloads/WinSys-0.4.win32-py2.6.msi

or you can just checkout the svn trunk:

svn co http://winsys.googlecode.com/svn/trunk winsys

To do what you describe (guessing slightly at the exact requirements) you could do this:

import codecs
from winsys import fs

base = "c:/temp"
with codecs.open ("permissions.log", "wb", encoding="utf8") as log:
  for f in fs.flat (base):
  log.write ("\n" + f.filepath.relative_to (base) + "\n")
  for ace in f.security ().dacl:
    access_flags = fs.FILE_ACCESS.names_from_value (ace.access)
    log.write (u"  %s => %s\n" % (ace.trustee, ", ".join (access_flags)))
