Thanks. I've tried
  self.login.credentialsChanged(reqd['username'],reqd['username'],reqd['password'])

Both before and after 
  self.acl_users.userFolderEditUser(reqd['username'],reqd['password'],'','')

And it doens't seem to help. The password never changes. Should I be calling 
credentialsChanged() as a method to something else? ('login' is the Cookie 
rumbler folder)

Does anyone have a working example code snippet?
