title: Login failed for existing user while adding database in Visual Studio
body: <p>I've created a new MVC project and am creating a new database by following <a href="http://nerddinnerbook.s3.amazonaws.com/Part2.htm" rel="nofollow">this</a> tutorial. But on adding an SQL Server Database, it gives the following error.</p>
  
  <p>"Login failed for user 'JM-VCACMASTER03\admin"</p>
  
  <p>I tried adding an existing database as given <a href="http://www.codeproject.com/Tips/496447/Linking-to-an-Existing-SQLDB-in-ASP-MVC-and-EF" rel="nofollow">here</a> and it adds it successfully. Whats going wrong with the first approach?</p>
