If set to None, the driver does not attempt to authenticate.
If set to Basic, the driver uses a hashed value, based on the concatenation of the user name and password, for authentication. In addition to the User and Password options, you must also configure the AuthHeader option if the name of your HTTP header is not Authorization (the default).
If set to HttpHeader, the driver passes security tokens via HTTP headers for authentication. You must also configure Security Token option and, if the name of your HTTP header is not Authorization (the default), the AuthHeader option.
If set to OAuth2, the driver uses OAuth 2.0 to authenticate to REST endpoints.
If set to UrlParameter, the driver passes security tokens via the URL for authentication. You must also configure the AuthParam and Security Token options.
If set to Custom, the driver uses a custom token-based authentication flow that is defined in the input REST file. See "Custom authentication requests" for more information on the input REST file.
Default
None
Note: The driver defaults to Custom when it discovers an entry for a custom authentication request in the input REST file.
