title: Restrict windows authentication to access a SQL Server database
body: <p>My SQL Server is operating in mixed mode, and I am accessing all my databases with Windows authentication, but I want to restrict one of my database to be accessed by Windows authentication and it should be accessed by SQL Server login user. </p>
  
  <p>I have created a new user and then assign him the rights to access database 
  from security tab. But this database is also accessible from Windows authentication.</p>
