Specifies the authentication method the provider uses when authenticating to the proxy server specified in the ProxyServer connection property.

Possible Values

Data Type

string

Default Value

"BASIC"

Remarks

Note: The driver only uses this ProxyAuthScheme when ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True, which is the default, the driver instead uses the authentication method specified in your system proxy settings.

The authentication type can be one of the following:

• BASIC: The driver performs HTTP BASIC authentication.
• DIGEST: The driver performs HTTP DIGEST authentication.
• NTLM: The driver retrieves an NTLM token.
• NEGOTIATE: The driver retrieves an NTLM or Kerberos token based on the applicable protocol for authentication.
• NONE: Set this when the ProxyServer does not require authentication.

For all values other than "NONE", you must also set the ProxyUser and ProxyPassword connection properties.

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