Adding multiple users to AD - powershell

Question

This script was working just fine today while testing. I made a few changes and started getting an error. I then went back to the very original script I got from the internet and now even it does not work. The errors are:
Exception calling "SetInfo" with "0" argument(s): "A constraint violation
occurred."

Here is the script. What am I doing wrong?
function Select-FileDialog {
param(
[string]$Title,
[string]$Directory,
[string]$Filter = "CSV Files(*.csv)|*.csv"
)
[System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") | Out-Null
$objForm = New-Object System.Windows.Forms.OpenFileDialog
$objForm.InitialDirectory = $Directory
$objForm.Filter = $Filter
$objForm.Title = $Title
$objForm.ShowHelp = $true
$Show = $objForm.ShowDialog()
if ($Show -eq "OK") {
return $objForm.FileName
} else {
exit
}
}
$FileName = Select-FileDialog -Title "Import an CSV file" -Directory "c:\"
$SelectOU = "OU=Test2,OU=Users,OU=Domain Controllers"
$domain = [System.DirectoryServices.ActiveDirectory.Domain]::GetComputerDomain()
$DomainDN = (([System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest()).Domains | ? {$_.Name -eq $domain}).GetDirectoryEntry().distinguishedName
$final = "LDAP://$DomainDN"
$DomainPath = [ADSI]"$final"
$UserInformation = Import-Csv $FileName
$OUPath = "LDAP://$SelectOU,$DomainDN"
$UserPath = [ADSI]"$OUPath"
foreach ($User in $UserInformation) {
$CN = $User.samAccountName
$SN = $User.Surname
$Given = $User.givenName
$samAccountName = $User.samAccountName
$Display = $User.DisplayName
$LABUser = $UserPath.Create("User", "CN=$CN")
Write-Host "Please Wait..."
$LABUser.Put("samAccountName", $samAccountName)
$LABUser.Put("sn", $SN)
$LABUser.Put("givenName", $Given)
$LABUser.Put("displayName", $Display)
$LABUser.Put("userPrincipalName", "$samAccountName#$domain")
$LABUser.SetInfo()
$Pwrd = $User.Password
$LABUser.psbase.invoke("setPassword", $Pwrd)
$LABUser.psbase.invokeSet("AccountDisabled", $false)
$LABUser.psbase.CommitChanges()
}
Write-Host "Script Completed"

Answer 1

Can you please try Removing the Quotes from
1) LABUser assignment i.e. CN = $CN.
2) Remove the CN = from that line.
Try it one by one i hope you get your answer.
