How to add users to ou in domain via Powershell Windows 2008

Before to use PowerShell you have to allow powershell scripts via policy, while there are lot of policies I just allow scripts on separate DomainController with higher access restritions
So you have to type in  PowerShell terminal

Set-ExecutionPolicy Unrestricted

So here are powershell script itself

Import-Module ActiveDirectory 
$Users = Import-Csv -Delimiter ";" -Path ".\userslist.csv"  
foreach ($User in $Users)  
{  
    $OU = "OU=yourou,DC=yourdomain,DC=comorothersuffix"  
    $Password = $User.password 
echo $Password
    $SPassword = ConvertTo-SecureString $Password -AsPlainText -Force 
echo $SPassword
    $Detailedname = $User.firstname
    $SAM =  $User.Name 
    New-ADUser -Name $Detailedname -SamAccountName $SAM -DisplayName $Detailedname -AccountPassword $SPassword -Enabled $true -Path $OU  
}
