title: Import a list of users from flat file to AD group
body: <p>I have two questions really, both surrounding the same topic.</p>
  
  <p>I need to be able to create a flat file and use this file to import the users listed in the file to a specific group in Active Directory.  They will already exist in AD, just not be in the group.</p>
  
  <p>Secondarily to that, I also need to be able to use similar methodologies to remove users from the AD group using a different flat file.</p>
  
  <p>Can this be done?  The list of users will be in the 100s so I really don't want to have to do it by hand....</p>
