Dear Andrew,

That's perfect! The reason for my asking this was actually twofold. 
First, this likely means a conceptual change, since xrootd (or part of it) then needs to stay running privileged to be allowed to chown() files, while right now it can run as dedicated xrootd user. 
Second, it seems CERN already has something like this in place (or they emulate it)... If I do (using Kerberos V auth): 
xrdcp some_local.file root://eosuser.cern.ch//eos/user/<letter>/<fullusername>/some_dest_file
the file "some_dest_file" is created on EOS as my user with my user group (albeit the file mode is always "0644" no matter the source file). 
Do you happen to know which technique they use to facilitate this basic ownership mapping? 

Cheers, many thanks and all the best,
	Oliver
