In my site I want Active directory authentication for auto login. Actually this site will be intranet so when user visit the site user should be automatically login in the site according to their authentication. 

I was able to synchronize the role and users of AD with nuke. And AD user can get logged in in the site. But he/she needs to click the login and goes through windows login for the AD users to get logged in  in the site.

I need automatic logged in of user when they visit the site according to their authentication in the AD.

And here I am hosting the site in one server and AD is in another server.
