title: SQL Server user best practice
body: <p>I have a login with Windows Authentication which is called domain\username. Now I want to map this login to my DB and the SSMS is proposing a user called domain\username as well.</p>
  
  <p>I don't know if I have to map the domain login to the database user as <strong>domain\username</strong> or simply as <strong>username</strong>.
  What is the best practice?
  THANKS</p>
