Authenticate Windows Authentication using Javascript

Question

I have to transfer my client from one website to another website. This happens in client side. In this 2nd website, its using windows basic authentication system. So It popups the login window. I need to omit this Popup window and authenticate my client on 2nd website using javascript and then redirect him to 2nd website. There is no security issue even I put credentials in javascript file since this whole system is running in Intranet. So How to authenticate client on 2nd website ?

I found this thread How can I pass windows authentication to webservice using jQuery?

But it does not work. When I look the request header of 2nd url, It does not contain the Authorization tag.

Answer 1

If this is Windows Authentication, then the response won't be prompting the client for credentials, the browser will be attempting to pass the credentials itself already. It does not quite work the way HTTP does -- you actually need to configure the browser itself to to have it send the authorization based on Windows credentials.

It does not appear that there is a simple JS solution to this at all.
