OK, but I'm still not 100% when the helper is actually called. Is the helper only used when a user is prompted for a password or is there an authentication process that takes place for each request? My thought is that our LAN users, since they are never forced to authenticate, are not effected by the children parameter but I wanted to double-check. Thanks, Andrew
