Hi Yannick, I think the DPM guys specifically prohibit direct access to an end node. You need to authenticate at the head node. That's how DPM is architected. Again, David Smith may have an alternative for you. But this is DPM doing it by design. Standard XRootD servers always authenticate at the end node not the head node (though one could configure it in DPM-like way but almost no one does).
