Powershell checking if OU exist

Question

I'm trying to check if an OU exist before creating it. My problem is that I have 2 mother OU "USER BY SITE" and "GROUP BY SITE", and I need to have the exact same OU in those 2, 1 for storing users, the other for storing groups.

So far I used this function :

function CheckOUExist
{
    param($OUToSeek)

    $LDAPPath = "LDAP://dc=Domain,dc=local"

    $seek = [System.DirectoryServices.DirectorySearcher]$LDAPPath
    $seek.Filter = “(&(name=$OUToSeek)(objectCategory=organizationalunit))”
    $Result = $seek.FindOne()

    return $Result
}

There is my problem, I always get the OU existing in "GROUP BY SITE" even if $LDAPPath = "OU=USERS BY SITE,DC=Domain,DC=local". Am I missing something there? Is there a way to for the [System.DirectoryServices.DirectorySearcher] to work only in the OU I gived in the $LDAPPath?

If you need more accurate detail, I'll gladly provide them.

Thank you in advance.

Try the Exists method, you get back true/false respectively:

[adsi]::Exists("LDAP://OU=test,DC=domain,DC=com")
