NTLM and Golang

I have recently learnt Go and I am experimenting with the net/http library. I have been trying to authenticate into a site using the http.SetBasicAuth function but it never seems to work. It works fine with cURL but not with Go. I know this has something to do with NTLM but I don't know how to fix the problem

cURL:

curl -v "http://server_that_im_trying_to_auth_with" --ntlm -u user:pass

Go: 

 req, _ := http.NewRequest("GET", "url", nil)
 req.SetBasicAuth(user, pass)
 resp, _ := http.DefaultClient.Do(req)
 body, _ := ioutil.ReadAll(resp.Body)

The body keeps on returning the sites 401 Page.

NTLM Authentication and Basic Authentication are not the same. NTLM is a protocol which is more complicated than just user:password string in header.
If you want to make a request from Golang code to authenticate you should use one of existing libraries, like: go-ntlmssp

Also you can read more about NTLM protocol itself here
