Authentication in Nodejs

[Sriharsha Sistalam]

Hi,

I am developing an application in nodejs for an enterprise company where most of the products, services uses Single Sign-On and supports only kerberos authentication. 

My application (A) needs to detect the user using the kerberos authentication and when application talks to other services (via http) like B, it has to send the authentication information so that Service B knows that the request is coming from application user A. Standard http module and request module only supports basic authentication, whenever I make any calls to service B from application A, they are failing with 401 error. Even the modules tagged as kerberos in npm ask for username and password. Please suggest if there is anyway to make authenticated calls from application A.
