Agreed - this appears to be a CMS internal issue.

That said, I suspect Andy's may be on the right path - make sure your CMS proxy exists before running the command. The auto-generated one from XRootD won't contain the VOMS extensions and hence may not be usable with CMS servers.

(But there are other potential causes that CMS experts can help with)

Can you please tell where in CMS could I report problems like this?

Hi,

it looks like a problem on the EOS side that is administered at CERN. The first point of contact to report this would be open up a ticket for CMS here:

https://ggus.eu/?mode=ticket_cms

And select CMS Support Unit "CMS AAA - WAN Access".

Hope this helps.

Thanks,
Marian
