Sample PowerShell Script: Automating User Account Creation

Here’s an example of a PowerShell script that demonstrates automating user account creation in Active Directory:

# Import the Active Directory module
Import-Module ActiveDirectory

# Function to create a new user account
function New-ADUserAccount {
    param(
        [Parameter(Mandatory=$true)]
        [string]$FirstName,
        
        [Parameter(Mandatory=$true)]
        [string]$LastName,
        
        [Parameter(Mandatory=$true)]
        [string]$Username,
        
        [Parameter(Mandatory=$true)]
        [string]$Password,
        
        [Parameter(Mandatory=$true)]
        [string]$OUPath
    )

    try {
        # Create a secure string for the password
        $SecurePassword = ConvertTo-SecureString -String $Password -AsPlainText -Force

        # Create the new user account
        New-ADUser -Name "$FirstName $LastName" `
                   -GivenName $FirstName `
                   -Surname $LastName `
                   -SamAccountName $Username `
                   -UserPrincipalName "$Username@yourdomain.com" `
                   -AccountPassword $SecurePassword `
                   -Enabled $true `
                   -Path $OUPath `
                   -ChangePasswordAtLogon $true

        Write-Host "User account created successfully for $FirstName $LastName"
    }
    catch {
        Write-Host "Error creating user account: $_"
    }
}

# Example usage
New-ADUserAccount -FirstName "John" `
                  -LastName "Doe" `
                  -Username "johndoe" `
                  -Password "P@ssw0rd123!" `
                  -OUPath "OU=NewUsers,DC=yourdomain,DC=com"

This script demonstrates several important concepts:

  • Importing and using the Active Directory module
