NTLM Authentication in Go HTTP Requests with System Credentials

In this question, the user seeks guidance on performing Windows NTML authentication in a Go HTTP request using the system credentials of the calling user. They provide examples from C# and Python that demonstrate how to achieve this in those languages.

The solution lies in utilizing the go-ole library, which enables the use of WinHTTPRequest in Go. By following a similar approach as the Python example, it is possible to implement NTML authentication with system credentials in Go.

Here is the provided code snippet in Go that accomplishes this:

package main

import (
    "fmt"

    ole "github.com/go-ole/go-ole"
    "github.com/go-ole/go-ole/oleutil"
)

func main() {
    ole.CoInitialize(0)
    defer ole.CoUninitialize()
    unknown, _ := oleutil.CreateObject("WinHTTP.WinHTTPRequest.5.1")
    request, _ := unknown.QueryInterface(ole.IID_IDispatch)
    oleutil.CallMethod(request, "SetAutoLogonPolicy", 0)
    oleutil.CallMethod(request, "Open", "GET", "http://example.com", false)
    oleutil.CallMethod(request, "Send")
    resp := oleutil.MustGetProperty(request, "ResponseText")
    fmt.Println(resp.ToString())
}

This code initializes the WinHTTPRequest object, sets the auto logon policy to use the current user's credentials, opens a GET request to the specified URL, sends the request, and retrieves the response text.
