广告密码中的聚会错误到期提醒

Question

这是代码的一部分，该代码如果用户的Active Directory密码即将到期。

它曾经起作用，但是现在我突然收到了这个错误！也许是因为当地的机器语言是德语的德语日期格式，但我不知道要修复它！我真的很感谢您的帮助。

代码：

#Calculate expirering passwords and store them in an object
$today = (get-date).date

[Threading.Thread]::CurrentThread.CurrentUICulture = 'en-US';

$ExpirePasswordList =
foreach ($ADUser in $AllADUsers) {
    $PasswordLastSet          = $ADUser.PasswordLastSet
    $PasswordExpireDate       = (get-date $PasswordLastSet).AddDays($MaxPasswordAge)
    $DaysBeforePasswordchange = (New-TimeSpan -start $today -end $PasswordExpireDate).days
    
    if ($DaysBeforePasswordchange -le $WarningLevel) {
        [pscustomobject]@{
            Givenname                = $ADUser.GivenName
            Surname                  = $ADUser.Surname
            MailAddress              = $ADUser.mail
            DaysBeforePasswordchange = $DaysBeforePasswordchange
            PasswordExpireDate       = $PasswordExpireDate 
        }
    }
}    

错误：

Get-Date : Cannot bind parameter 'Date' to the target. Exception setting "Date": "Cannot convert null to type "System.DateTime"."

正如 theo 所建议的那样正确 $ passwordlastset 结果是null beacuse beacuse您未提及password> passwordlastset < /code>属性在其 - 属性 get -aduser的参数中，并插入变量$ alladusers。

尝试以下PowerShell代码，它应该为您工作。

$AllADUsers=get-aduser -filter * -properties passwordlastset, passwordneverexpires | ft GivenName,Surname,mail,passwordlastset, Passwordneverexpires

$ExpirePasswordList =
foreach ($ADUser in $AllADUsers) {
    $PasswordLastSet          = $ADUser.passwordlastset
    $PasswordExpireDate       = (get-date $PasswordLastSet).AddDays($MaxPasswordAge)
    $DaysBeforePasswordchange = (New-TimeSpan -start $today -end $PasswordExpireDate).days
    
    if ($DaysBeforePasswordchange -le $WarningLevel) {
        [pscustomobject]@{
            Givenname                = $ADUser.GivenName
            Surname                  = $ADUser.Surname
            MailAddress              = $ADUser.mail
            DaysBeforePasswordchange = $DaysBeforePasswordchange
            PasswordExpireDate       = $PasswordExpireDate 
        }
    }
}
