Useful PowerShell Script to Bulk Create Users

Just used this script to generate 4000 users accounts within a development Active Directory.

The CSV has to be in the format:

##### CSV FILE ########

Name,Firstname,Password

User1,test,P@$$w0rd!1

User2,test,P@$$w0rd!1

User3,test,P@$$w0rd!1

User4,test,P@$$w0rd!1

############### START SCRIPT ################

Import-Module ActiveDirectory

$Users = Import-Csv -Delimiter “;” -Path “.\users.csv” 

foreach ($User in $Users) 

{ 

    $OU = “OU=Employees,DC=lab-os,DC=com” 

    $Password = $User.password

    $Detailedname = $User.firstname + " " + $User.name

    $UserFirstname = $User.Firstname

    $FirstLetterFirstname = $UserFirstname.substring(0,1)

    $SAM =  $FirstLetterFirstname + $User.name

    New-ADUser -Name $Detailedname -SamAccountName $SAM -UserPrincipalName $SAM -DisplayName $Detailedname -GivenName $user.firstname -Surname $user.name -AccountPassword (ConvertTo-SecureString $Password -AsPlainText -Force) -Enabled $true -Path $OU 

}
