Creating Realistic Test User Accounts in Active Directory

When you need to simulate a real Active Directory with thousands of users you quickly find that creating realistic test accounts is not trivial. Sure enough, you can whip up a quick PowerShell one-liner that creates any number of accounts, but what if you need real first and last names? Real (existing) addresses? Postal codes matching phone area codes? I could go on. The point is that you need two things: input files with names, addresses etc. And script logic that creates user accounts from that data. This blog post provides both.

Mission Statement

The purpose of the script is to create an arbitrary number of user accounts with the following properties:

  • Logon name (sAMAccountName)
  • User principal name (UPN)
  • First name
  • Last name
  • Display name
  • E-mail address
  • Street
  • City
  • Postal code
  • State
  • Country
  • Phone number
  • Company
  • Department
  • Title

The accounts should be created in a specified OU; they should have a password and be enabled. The end result should look like this:

Active directory user accounts created by the PowerShell script

Realism

In order to create realistic results we need data, lists: male names, female names, surnames, addresses and a mapping between postal and phone area codes. The script CreateDemoUsers.ps1 expects separate CSV files for each of these. For Germany I have compiled the necessary lists, they can be downloaded here.

If you want your users to “live” in another country you need to provide the lists yourself.

Using CreateDemoUsers.ps1

Running the script is simple enough: just start it, there are no commandline parameters. I have run it directly on my lab’s domain controller but it should work from a domain member, too.

Before you execute the script you might want to configure a few things, though. Take a look at the global variables section at the head of the script:

#
# Global variables
#
# User properties
$ou = "OU=Users,OU=Test,OU=HK,DC=hk,DC=test" # Which OU to create the user in
$initialPassword = "Password123"             # Initial password set for the user
$orgShortName = "AC"                         # This is used to build a user's sAMAccountName
$dnsDomain = "acme.com"                      # Domain is used for e-mail address and UPN
$company = "ACME Corp."                      # Used for the user object's company attribute
$departments = (                             # Departments and associated job titles to assign to the users
                  @{"Name" = "Finance & Accounting"; Positions = ("Manager", "Accountant", "Data Entry")},
                  @{"Name" = "Human Resources"; Positions = ("Manager", "Administrator", "Officer", "Coordinator")},
                  @{"Name" = "Sales"; Positions = ("Manager", "Representative", "Consultant")},
                  @{"Name" = "Marketing"; Positions = ("Manager", "Coordinator", "Assistant", "Specialist")},
                  @{"Name" = "Engineering"; Positions = ("Manager", "Engineer", "Scientist")},
                  @{"Name" = "Consulting"; Positions = ("Manager", "Consultant")},
                  @{"Name" = "IT"; Positions = ("Manager", "Engineer", "Technician")},
                  @{"Name" = "Planning"; Positions = ("Manager", "Engineer")},
                  @{"Name" = "Contracts"; Positions = ("Manager", "Coordinator", "Clerk")},
                  @{"Name" = "Purchasing"; Positions = ("Manager", "Coordinator", "Clerk", "Purchaser")}
               )
$phoneCountryCodes = @{"DE" = "+49"}         # Country codes for the countries used in the address file

# Other parameters
$userCount = 5000                            # How many users to create
$locationCount = 20                          # How many different offices locations to use

# Files used
$firstNameFileMale = "Firstnames-m.txt"      # Format: FirstName
$firstNameFileFemale = "Firstnames-f.txt"    # Format: FirstName
$lastNameFile = "Lastnames.txt"              # Format: LastName
$addressFile = "Addresses.txt"               # Format: City,Street,State,PostalCode,Country
$postalAreaFile = "PostalAreaCode.txt"       # Format: PostalCode,PhoneAreaCode

There you can configure important things like how many users to create, which OU to create them in, how many different addresses to use and many other things. That section also contains the names of the data files the script requires. If you use my files you do not need to change anything, but if you create your own files you might want to make sure the file names match.

Script Output

When you run the script it prints the users as it creates them. That looks like this:

Download

As the script is a little bit long for printing it here I have made it available for download.

You might also want to check out an extended version of the script which is maintained by Rob Bridgeman on GitHub.

Have fun!
