Connect to OpenLDAP Linux Server from Windows Powershell

My OpenLDAP server is setup in Linux. I want to connect to it from Windows 10 through Powershell This is the code snippet that I'm using

$path = 'LDAP://xxx.xxx.x.xxx:xxx/dc=xyz,dc=com'
$username = 'admin'
$password = 'password'
Try{
    $root = [adsi]::new($path,$username,$password)
    $searcher = [adsisearcher]$root
    $searcher.findone()
}
Catch{
    Write-Host "ERROR: $_"
}

I'm getting the following error -

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

My aim after connecting to the server is to perform the equivalent of 'ldapsearch' and retrieve the LDAP Password Policy setup in the OpenLDAP server.
