Login functionality where we can login using MS ID/Password.

Question

I have created a website which is to be used internally in my company. Log-in Id and password to be used should be the same (Microsoft)MS ID/Password employees use to log-in their computer. How to put this functionality in the website ?

 

I have used

<authentication mode="Windows" /> in web.config and hosted the website on my machine's IIS . 

 

I need the Login functionality with the username / password field, so the user can enter his MSID & password and click on login button. 

 

I am unable to figure out, please help.
