Customer requested to force active directory accounts to expire on midnight or in the night and not during the day. So I’ve created following script to do so:

$UserList = Get-ADUser -Filter * -SearchBase "OU=USERS,DC=domain,DC=local" -Properties "DisplayName", "PasswordLastSet"
$Today = (Get-Date)
$MaxPasswdAge = (Get-ADDefaultDomainPasswordPolicy).MaxPasswordAge

ForEach ($User in $UserList)
   {
   $ExpireDate = ($User.PasswordLastSet) + $MaxPasswdAge
   $DaysToExpire = (New-TimeSpan -Start $Today -End $ExpireDate).Days
   If ($DaysToExpire -eq 1)
      {
      Set-ADUser -Identity $User -ChangePasswordAtLogon $true
      }
   }

#EOF

This script runs everyday at 23:55.

I found couple examples how to change pwdLastSet attribute on AD user’s object, but I don’t like that. I think this is cleared way to do so.

Have a nice day,
