Dear Stefano,

have you tried to do this in an External Method rather than in a script? Scripts have security checks which are not applied to external methods. This can be a little help in solving the problem.

Indeed. The script I gave in my original email < http://groups.yahoo.com/group/zope/message/54291 > isn't actually a Zope Python Script. It's just a standalone bit of Python that I can't get to work. Technically, I suppose, I'm having problems with the win32security module (I'm still keen to find some documentation if anyone can point me in the right direction), rather than Zope, but I was hoping someone here would have had similar problems. Cheers, Ian
