title: SSRS Data Driven File share account - impersonation error
body: <p>I am setting up SSRS data driven subscription with windows file share delivery option.</p>
  
  <p>In regular SSRS subscriptions with windows file share delivery there is an option to use file share account credentials - seems that is missing in data driven subscriptions section</p>
  
  <p>So, when I setup data driven subscription I am getting below error (but it works fine with regular subscription)</p>
  
  <p>ERROR: Error occurred processing subscription Failure writing file : An impersonation error occurred using the security context of the current user.</p>
