[Zope] External Method Problem

6 Jul 2001

      Hello,

I've a external method called 'getUserGroups', for the code of this method look at the end of this message, and when I call this method with:

<dtml-var "getUserGroups (REQUEST['REMOTE_USER'])">

i get this error:

Traceback (innermost last):

Is this an error or a Security Feature of External Methods?

--- getUserGroups.py:

import win32net
import string

def getUserGroups (self, canon_username):

	tmp = []
	groups = []
	dc = ''
	server = ''
	username = ''

	if string.find (canon_username, '\\') != -1:
		tmp = string.split (canon_username, '\\')

		if (len (tmp) == 2):
			dc = tmp [0]
			username = tmp[1]

	server = win32net.NetGetDCName ('', dc)

	groups = win32net.NetUserGetGroups (server, username)

	return groups

Thanks and greetings
