Powershell/LDAP finding all never expiring users in Active Directory (AD)

Another very useful powershell script that pulls all the users that are set their password to never expire. 

One key thing on this script is making sure that you filter out service accounts because you don't need them every single time. so for instance if your employee numbers allways start with a E then you could add (employeeID=e*) to the ldap filter. and this will pull only employeeID field from ad with the employee ID that starts with *

takes all user accounts that employee id that starts with a e and has never expire password checked.

$date1 = Get-Date -Date "01/01/1970"
$date2 = Get-Date
$start = (New-TimeSpan -Start $date1 -End $date2).TotalSeconds

Write-Output "first_name,last_name,email_address,employee#" |  out-file .\users.csv -force
$server = "yourdomaincontroler"
$root = [ADSI]"LDAP://OU=Accounts,DC=domain,DC=local"
$search = [adsisearcher]$root
$Search.Filter = "(&(objectCategory=person)(sAMAccountType=805306368)(employeeID=e*)(userAccountControl:1.2.840.113556.1.4.803:=65536))"
$colResults = $Search.FindAll()

foreach ($i in $colResults)
 [string]$i.Properties.Item('givenName'),[string]$i.Properties.Item('sn'),[string]$i.Properties.Item('mail'),[string]$i.Properties.Item('samaccountname') -join "," |  out-file .\users.csv -append

Write-Output "Done - output to users.csv"
$date1 = Get-Date -Date "01/01/1970"
$date2 = Get-Date
$end = (New-TimeSpan -Start $date1 -End $date2).TotalSeconds
$completed = $end - $start
Write-Output "Done - output to users.csv - Finished in seconds" $completed

Hopefully this helps you keep track of everyone that has never expiring passwords and then you can get them so they don't . no reason to have exceptions for users in your password policy. As this only increases the risk to your company. 
LDAP note using (sAMAccountType=805306368) is faster than using (objectclass=user)
