[xrootd: could not authorize using gsi: provider was not found]

[AnthonyAportela]

When trying to access a root file, I get the following error

julia> f = ROOTFile("root://cmsxrootd.fnal.gov//store/group/[some_directory]/rootfile.root")
2022/08/20 18:50:53 xrootd: could not authorize:
[xrootd: could not authorize using gsi: provider was not found]

So usually when I see something like this, it's because I didn't initialize the voms proxy (maybe just cms specific). But I think that shouldn't be an issue, since I initialize it before running the above commands.

Any idea what this might be?

For root:// protocol, we use the Go backend for reading over network, so we should probably figure out what environmental variable it uses.

Any chance you can use http:// protocol and sci-token? This uses pure Julia HTTP.jl

oh yeah you need something else because:

• xrootd: authentication go-hep/hep#250

gsi is not implemented

any known work around? @sbinet

[sbinet]

• implement gsi
• implement sci-token

probably implementing sci-token would be easier (IIRC, it has "modern" specs and uses a "modern" underlying protocol that is more in line with what Go libraries are expecting.)

I don't think sites are enabling scitoken anytime soon
