nodejs ntlm get a user's groups

Question

I am using express-ntlm. The authentication with the domain controller is working fine. But I need to get authenticated user's group details. Actually a particular group will be authorised.

I found some examples example 1example 2

But it seems using node-activedirectory I need to know user's password. But can I do it without using user's password? Or is there anyway to get password from ntml?

Answer 1

No, NTLM never provides passwords. Its just a way of User authentication using 3 way handshaking inside a corporate network.
