title: deployment of adventureworks cube fails: 'user does not have permission to create a new object in 'GARY-PC' or the object does not exist
body: <p>when I deploy adventure works cube it fails, and i get: user does not have permission to create a new object in 'GARY-PC', or the object does not exist. 
  trying to process cube from adventureworks DW and having what seem like permissions issues (?). 
  took following steps (i am using sql server 2008 R2 developer edition and VS 2008):
  1 downloaded and successfully created adventureworksDW (2008R2) database from
  2 successfully created Datasource and DSV for a cube with 2 fact tables and several dimensions. 
  3 Click deploy  </p>
  
  <p><strong>I see the following 2 prompts</strong>
  Login: greyed out, can’t type anything here
  the password is required for the impersonation account of data source Adventure Works DW. </p>
  
  <p>Now, Whether I enter  a password or not, I get:
  Error   3   Either the 'Gary-PC\Gary' user does not have permission to create a new object in 'GARY-PC', or the object does not exist.      0   0   </p>
  
  <p>what objects is SSAS trying to create? are these objects in the relational database? </p>
