powershell - 检查OU是否存在无法正常工作

Question

编写此小脚本以测试OU是否存在，是否存在OU写入控制台并终止。如果不存在，则创建OU并执行其他操作。虽然似乎无法理解为什么我无法正常工作。

由于某种原因，输出将始终告诉我该OU存在，并且我很确定它不存在。我做错什么了吗？

这是代码:

param (
    [parameter(mandatory=$true)] [string] $servername
)

Import-Module ActiveDirectory

Function CheckOU {
    $script:OUpath = "OU=$servername,OU=Rechtengroepen,OU=danny,dc=Doenoe,DC=com"
    $Status = $false
    $GetOU = Get-ADOrganizationalUnit -Identity $OUpath -ErrorAction SilentlyContinue

    if ($GetOU -eq $null) {
        $status = $false
        Write-Host -ForegroundColor Green "$OUpath does not exist." 
    } else {
        $Status = $true
        Write-Host -ForegroundColor Red "$OUpath exists!"
    }
    return $Status
}

$OUStatus = CheckOU

if ($OUStatus -eq $true) {
    Write-Host "$OUpath exists. Function working."
} else {
    Write-Host "$OUpath does not exsist, do something."
}

输出:

Get-ADOrganizationalUnit : Directory object not found

如果具有给定标识的对象不存在，则将cmdlet与-Identity参数一起使用会导致终止错误。使用-Filter可以避免此问题:

Get-ADOrganizationalUnit -Filter "distinguishedName -eq '$OUPath'"
