Supports only NTLMv1? or supports NTLMv2 as well?

Hello Sam,

My SharePoint site uses NTLMv2 & on the IIS server ‘lmcompatibilitylevel’ registry is set as ‘5’.

This module supports only NTLMv1? I see that in the code the naming convention is as below.

create_LM_hashed_password_v1

Wondering if this only supports NTLMv1.

I am getting always 401 Unauthorized from SharePoint site & its passing all handshake including type3 message. But the response comes as 401.

I can confirm that this does not work with NTLM v2. This project seems to support v2, but it is not working for me for some reason. I just started looking into the code, and if get it working I’ll follow up here, on what can be done to support NTLM v2.

I use it in my own module, so you can dig into the file OnpremiseUserCredentials.ts for a real usage example.

The class itself performs NTLM auth and returns credentials via Authorization header. You can attach that header to your ongoing http request against NTLM protected resource. keep alive agent also seems required.
