Authenticate Active Directory users without asking username and password

Question

Is there any way that we can authenticate Active Directory user automatically without username and password say by getting his PC name (RF18-PC\RS-Vivekh).

Here is what i am trying to achieve. I have an application where users can login by entering his details. I want to implement other type of login through Active Directory where initially i will configure my AD and will add some users within my LAN giving a name and will store the info in database and then the user login to the system with that username and password and can go to our web page and my app will automatically detects by getting the PC-NAME and will look into the database and detects whether there is corresponding user in the db with that name then i will automatically get the User details and pass it to PrincipalContext to verify whether he exists in AD. if he exists then he will go to the home page directly. Is this achievable

Answer 1

In IIS you can use the security option to use windows authentication to automatically check the user that is logged in. You will also have to change the settings to use NTLM over Negotiate.

Is this what you ment?
