title: Limit SQL Azure access to Roles within the same subscription only
body: <p>I would like to limit access to my SQL Azure databases to only roles that are within the same subscription.</p>
  
  <p>It seems the 'Allow other Windows Services to access this server' (0.0.0.0 - 0.0.0.0) rule would allow access attempts from any role within any subscription. </p>
  
  <p>Is there currently any way to limit connection attempts to only my roles? If not what protection does SQL Azure offer against hostile roles?</p>
