NTLM (alternative)

NTLM handshake authentication

The default NTLM authentication uses go-ntlmssp - the great package by Azure team. However, we found rare environments where it fails for some reason. Fortunately, there is an alternative.

Usage sample

package main

import (

	strategy "github.com/koltyakov/gosip-sandbox/strategies/ntlm"

func main() {

	authCnfg := &strategy.AuthCnfg{
		SiteURL:  os.Getenv("SPAUTH_SITEURL"),
		Username: os.Getenv("SPAUTH_USERNAME"),
    Domain:   os.Getenv("SPAUTH_DOMAIN"),
		Password: os.Getenv("SPAUTH_PASSWORD"),

	client := &gosip.SPClient{AuthCnfg: authCnfg}
	sp := api.NewSP(client)

	res, err := sp.Web().Select("Title").Get()
	if err != nil {

	fmt.Printf("Site title: %s\n", res.Data().Title)


Use the alternative only as a fallback method if go-ntlmssp doesn't work and don't forget to post an issue to help making Open Source tools better.
