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 connector only uses this ProxyAuthScheme when ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True (the default), the connector instead uses the authentication method specified in your system proxy settings.

Supported authentication types :

• BASIC: The connector performs HTTP basic authentication.
• DIGEST: The connector performs HTTP digest authentication.
• NTLM: The connector retrieves an NTLM token.
• NEGOTIATE: The connector retrieves an NTLM or Kerberos token based on the applicable protocol for authentication.
• NONE: Signifies that 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.
