body: <p>I am Using Visual Studio Data Tool and trying to create a SSAS project so I created data source and use my SQL Authentication to access the Data source
  and i choose the service access as impersonation access to deploy the cube</p>
  
  <p>I have got this error when i deployed the cube</p>
  
  <blockquote>
    <p>Error  6   OLE DB error: OLE DB or ODBC error: Login failed for user 'NT Service\MSSQLServerOLAPService'.; 28000.      0   0   </p>
  </blockquote>
  
  <p>I checked the SQL Management studio and I didn't find the service account for Analysis services which is <strong>NT Service\MSSQLServerOLAPService</strong> only i found a user named <strong>MSSQLServerOLAPService</strong> then i added new user in SQL Data Base named <strong>NT Service\MSSQLServerOLAPService</strong> and i have deployed the cube but i got the same error message.</p>
