The authentication type to use to authenticate to the ProxyServer proxy.
Possible ValuesBASIC, DIGEST, NONE, NEGOTIATE, NTLM, PROPRIETARY
Note that the provider will use the system proxy settings by default, without further configuration needed; if you want to connect to another proxy, you will need to set ProxyAutoDetect to false, in addition to ProxyServer and ProxyPort. To authenticate, set ProxyAuthScheme and set ProxyUser and ProxyPassword, if needed.
The authentication type can be one of the following:
- BASIC: The provider performs HTTP BASIC authentication.
- DIGEST: The provider performs HTTP DIGEST authentication.
- NEGOTIATE: The provider retrieves an NTLM or Kerberos token based on the applicable protocol for authentication.
- PROPRIETARY: The provider 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.
