Hi All:MyCustomer met a problem here: Part of our security for the wireless network is setting the Remote access Permission(Dial-in or VPN)in Active Directory User profile to Deny Access. This DOES block users on a Windows PC. However, it does NOT block users on Mac OS.The Network environment is we will authenticate the user can access wireless or not by windows IAS.Anyone can tell me we canalso apply thisfeature (Remote access Permission) to Mac OS ? as i suspect this is a problem of compatibility between Mac OS and Windows AD.sam
