PowerShell AD User Search
Had a buddy ask me for a quick PowerShell script the other day and I was happy to oblige, as I rarely get to write PowerShell these days and I really enjoy it. So without further adieu, here is a quick and dirty script that takes a CSV file with first names, middle initials, and last names, then spits out a simple text file of exact matches in AD. Great for environments where only a few users had accounts in the past and now for whatever reason you want to give everyone an account or something. It's not the most efficient or flexible script, but it might come in handy for someone.
