How to authenticate current user with Active Directory?

Question

I want to authenticate the current user using Active Directory, I don't want to use user password. If a user logged in the system then it should check for active directory whether the user is valid or not. I have got lots of code but they are using password..

Kindly help.

Take a look at a similar question: https://webmasters.stackexchange.com/questions/31866/active-directory-auto-login-to-website-for-domain-users

Both the above examples do not use any password to login.

If your Internet Explorer still asks you for login details then it can be because of your IE settings:

In Internet Explorer go to Tools -> Internet Option -> Security -> Custom Level -> Scroll down to the bottom and select "Automatic Login with current user name and password” -> OK -> OK -> Close and reopen browser.

This should allow an AD authenticated user to pass straight through to your page.
