Remarks

This value specifies the authentication type to use to authenticate to the HTTP proxy specified by ProxyServer and ProxyPort.

The authentication type can be one of the following:

• BASIC: The driver performs HTTP BASIC authentication.
• DIGEST: The driver performs HTTP DIGEST authentication.
• NEGOTIATE: The driver retrieves an NTLM or Kerberos token based on the applicable protocol for authentication.
• PROPRIETARY: The driver does not generate an NTLM or Kerberos token. You must supply this token in the Authorization header of the HTTP request.

If you need to use another authentication type, such as SOCKS 5 authentication, see FirewallType.
