检查是否存在工作不正常的OU

Question

编写这个小脚本来测试OU是否存在，如果存在则写入控制台并终止。如果不存在，创建OU并做一些其他事情。虽然我似乎不明白为什么我不能让它工作。

由于某种原因，输出总是告诉我OU存在，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:

如果具有给定标识的对象不存在，则使用带有-Identity参数的cmdlet会导致终止错误。使用-Filter来避免这个问题:

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