title: How can I totally delete a user from Sharepoint 2010?
body: <p>I  can delete a user from a site collection, but I can't seem to delete a user totally from SharePoint.</p>
  
  <p>For example:</p>
  
  <p>Let's say DOMAIN\joetest has a user ID of 15. I can delete that account from the site collection (via web gui or powershell), but the next time that account is ensured the ID is still 15.</p>
  
  <p>Is there a way to totally delete a user from SharePoint? So, the next time the account is ensured it has a new ID (say 150 instead of 15).</p>
  
  <p>Is that even possible.</p>
