Clear-Host
$pwpsModule = Get-Module pwps
    if (!$pwpsModule)
        {
        Import-Module pwps
        }


foreach ( $datasource in (Get-PWDatasource) )
{
if (($datasource.HostName -eq 'xxxx.local') -and ($datasource.InternalName -eq 'zTests_xxx'))
    {

    write-host "Traitement de $($datasource.InternalName)" -BackgroundColor darkGreen

    $cnx=(Open-PWConnection -DatasourceName $datasource.FullName -UserName 'zAdm_xx' -Password 'xxxxxx' -ErrorAction SilentlyContinue)

    if ($cnx)
        {
        Get-PWUser | where { $_.IsConnected }
        Close-PWConnection
        }
        else {write-host "   -> Erreur de connection" -ForegroundColor DarkMagenta}
