Powershell: foreach not working. Why?

Question

PowerShell

There is a script:

$sourceOU = "OU=Workstations,OU=11,OU=Filials,DC=domain,DC=local" 
$destinationOUs = Get-Content C:\ou.txt
foreach ($destinationOU in $destinationOUs)
{
$adPath= "LDAP://" + $destinationOUs 
import-module activedirectory 
#Create OUs 
$objDomain=New-Object System.DirectoryServices.DirectoryEntry($adPath) 
$ObjSearch=New-Object System.DirectoryServices.DirectorySearcher($ObjDomain) 
[array] $OUs = @() 
$OUs = dsquery * $sourceOU -Filter "(objectCategory=organizationalUnit)" -limit 0 
$OUsorted = $OUs | sort-object { $_.Length} 
for ($k=0; $k -le $OUsorted.Count -1; $k++) 
{ 
    $OUtoCreate = ($OUsorted[$k] -replace $sourceOU,$destinationOUs).ToString() 
    $OUSearch = ($OUtoCreate -replace '"',"").ToString() 
    $ObjSearch.Filter = "(&(objectCategory=organizationalUnit)(distinguishedName="+ $OUSearch + "))" 
    $allSearchResult = $ObjSearch.FindAll() 
    if ($allSearchResult.Count -eq 1) 
    { 
        "No changes were done on = " + $OUtoCreate 
    } 
    else 
    { 
        dsadd ou $OUtoCreate 
        "OU Creation = " + $OUtoCreate 
    } 
} 
}

There is a file containing a list of $sourceOU , like: OU=Workstations,OU=11,OU=Filials,DC=domain,DC=local on each line. But it only works if there is only one value in the file. If two or more does not work. I can't figure out why :(

Gives an error message:

Exception calling "FindAll" with "0" argument(s): "Unknown error (0x80005000)"

OU Creation = "OU=Workstations,OU=22,OU=Filials,DC=domain,DC=local OU=Workstations,OU=Ag. Krilatskoe,OU=Filials,DC=domain,DC=local"

Where am I wrong? Where is wrong?

Answer 1

In the $adPath= "LDAP://" + $destinationOUs line, you specified $destinationOUs this variable contains the entire OU array, you should have specified $destinationOU
Similar problems can be easily detected by replacing executable commands with simpler ones, for example Write-Host variable name, immediately everything falls into place and it is clear what is coming from

Answer 2

1. Open the script in Powershell ISE, there is functionality for debugging scripts.
2. Powershell has a native cmdlet for creating an OU - New-ADOrganizationalUnit, why mess with dsadd.
