ASP.NET - login failed for the user 'username'

Hi 


I have created a windows authentication for my application and I have used my credentials in the applicationpool identity and I have not added my login credentials in the database and hence I am getting the following exception 


Login failed for the user 'username'.


I want to know whether it is possible to perform windows authentication without adding the login credentials in the database

Use a sql user to connect to your database instead of windows authentication.
