Hello, This is a bit of a low-level suggestion, but can the xrootd unix user write to /data? I had similar looking issues with a test xrootd server and a known working config where I had forgotten to chown the exported path. My apologies for the noise if you've already checked this. Cheers, Matt ________________________________________ From: [log in to unmask] <[log in to unmask]> on behalf of Dejan Vitlacil <[log in to unmask]> Sent: 08 February 2023 09:24 To: Oliver Freyermuth Cc: [log in to unmask] Subject: [External] Re: XRootD and tokens This email originated outside the University.
