In some cases, it might be desirable to make the owner of the file the same as the user who uploads the file.
To enable this option, add this setting to cloudconfig.php
define("TONIDO_NETWORKSHARE_ASSIGN_UPLOAD_OWNER", 1);
If set owner doesn't work, make sure to add the service account that runs the web server to the local administrators group in your Windows file share servers or run it as a domain admin.
