Hello, I want to write a login script which authentificates with a exUserFolder. But I get this error message: Zope has encountered an error while publishing this resource. Error Type: TypeError Error Value: object does not support item or slice assignment The Log says that the error is on line 5, marked with <--. ## Script (Python) "loginUser" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters=REQUEST=None ##title= ## if REQUEST == None: REQUEST = context.REQUEST RESPONSE = REQUEST.RESPONSE REQUEST['__ac_name'] = REQUEST['username'] <-- REQUEST['__ac_password'] = REQUEST['password'] try: # Login successfull. userObject = self.acl_users.validate(REQUEST) RESPONSE.redirect('loginok.zpt') except: # Login failed... authFailedCode=REQUEST.get('authFailedCode', '') RESPONSE.redirect('loginfailed.zpt?authFailedCode=%s'%(authFailedCode)) What is wrong? Thx, Florian
