nginx reverse proxy with Windows authentication that uses NTLM

Question

Anyone knows if is possible to do reverse proxy with Windows authentication that uses NTLM? I cant find any example on this. What should be the values of more_set_headers fi

Answer 1

According to nginx documentation:

Allows proxying requests with NTLM Authentication. The upstream connection is bound to the client connection once the client sends a request with the “Authorization” header field value starting with “Negotiate” or “NTLM”. Further client requests will be proxied through the same upstream connection, keeping the authentication context.

upstream http_backend {
    server 127.0.0.1:8080;

    ntlm;
}

but the ntlm; option is available only with a commercial subscription (Nginx Plus)

You can use this module for non-production environments.

gabihodoroaga/nginx-ntlm-module

The module is not complete but it was enough for me to solve my issues.
