title: Recieving CREATE USER error when attempt to import BACPAC from blob storage to ssms
body: <p>I am attempting to backup and restore a database located in Azure SQL database via Azure blob storage. To do this I have run <code>Export Data-Tier Application...</code> on the selected database and successfully stored it in a blob container as a BACPAC file. Now I am trying to do the reverse and Import <code>Data-Tier Application...</code> to check the backup process functions correctly, however I receive the following error during the process:</p>
  
  <blockquote>
    <p>Could not import package.</p>
    
    <p>Error SQL72014: .Net SqlClient Data Provider: Msg 15063, Level 16,
    State 1, Line 1 The login already has an account under a different
    user name.</p>
    
    <p>Error SQL72045: Script executation error. The executed script: CREATE
    USER [username] FOR LOGIN [username];</p>
    
    <p>(Microsoft.SqlServer.Dac)</p>
  </blockquote>
  
  <p>This results in the <code>Importing database</code>, <code>Importing package schema and data into database</code> and <code>Updating database</code> operations failing, and the creation of an empty database.</p>
  
  <p>I'm unsure where the login or creating a user becomes relevant in importing the database, do you know why this error is occuring?</p>
