#.SYNOPSIS
#   Generate realistic-looking random user and computer accounts in AD.
#
#.DESCRIPTION
#   Creates random user and/or computer accounts in Active Directory 
#   with somewhat realistic properties in the top-level OU of your
#   choice.  If the OU does not exist, it will be created; the OU
#   defaults to "NewEmployees" if another target OU is not given.
#
#.NOTES
# Requires: PowerShell 2.0 or later, Server 2008-R2 or later domain controller,
#           and you must run the script on the controller as a Domain Admin
#           for the domain in the forest where you want the accounts created.
#  Version: 1.0
#   Author: Jason Fossen (https://BlueTeamPowerShell.com)
#  Warning: If you target an existing production OU, the script will
#           create accounts in that OU alongside your real accounts. Also,
#           the users will be created with long but predictable passphrases in
#           the format of "phonenumber Pw phonenumber" using each user's 
#           unique and world-readable phone number -- You've Been Warned!
#    Legal: 0BSD.
#Requires -Version 2.0
