Notes
 * Also disable Windows NT Challenge/Response authentication (NTLM). The only authentication must be set to Basic (Clear Text) authentication.
 * When you use Basic authentication, we strongly recommend that you use Secure Sockets Layer (SSL). In Basic authentication, the user name and the password are sent in clear text and may be captured by network-monitoring software. Therefore, use SSL so that the user name and the password are encrypted and cannot be read if they are captured by network-monitoring software.
