If the credentials map to an allowed group the person surfs wherever they wish, otherwise the client IP is checked against allowed sites. If the client IP is listed in SURFING they are allowed to surf wherever they wish, otherwise their destination domain is checked against allowedsites. If found, the request is allowed. So to be denied, it has to be someone not in an authorized LDAP group, surfing from a computer not in the SURFING IP range going to a site not listed in allowedsites. In any case, all transactions are logged to whatever name the surfer provided to the authentication request. That should about cover it... Chris
