hi, So, my understanding is that the authorisation via the head node happens because the /etc/xrootd/xrootd-dpmdisk.cfg contains the line: ofs.authlib libXrdDPMDiskAcc.so.3 There's no reason why you can't run another "basic" xrootd client on one or more disk servers (in addition to the one that talks to DPM head for authentication). You'll need to make another config file in /etc/xrootd/, configuring the service as a "standalone" xrootd, and probably change the xrd.port to a number different to 1095 so it doesn't conflict with the DPM service. (And then add a new configuration variable to /etc/sysconfig/xrootd: XROOTD_MYXROOTD="-l /var/log/xrootd/xrootd.log -c /etc/xrootd/xrootd-myxrootd.cfg" and the relevant token to XROOTD_INSTANCES XROOTD_INSTANCES="disk myxrootd" ) AFAICT, restarting xrootd at this point should bring the "disk" instance up, along with your new "myxrootd" instance. (Do ask David Smith before doing this if you're at all worried, though, although rolling back will just be a matter of removing the "myxrootd" from XROOTD_INSTANCES and restarting xrootd on the server again).
