Problem with Permission with coffea-casa on UChaicago AF

[MoAly98]

Hello!

I have some problems with my permissions on the UChicago AF which I am not sure how to resolve.

So I have the following file

file = "root://eosatlas.cern.ch//eos/atlas/atlascerngroupdisk/phys-higgs/HSG8/tH_v34_minintuples_v0/mc16a_nom/410470_AFII_user.vvecchio.27456668._000001.output.root"

which I am trying to open on the UChicago coffea-casa. I can open the file easily with:

uproot.open(file)

no problems. However If I try to open the same file with ServiceX for example, I use:

from func_adl_servicex import ServiceXSourceUpROOT
ds = ServiceXSourceUpROOT(file, treename="nominal_Loose")
data = (ds
    .Select("lambda e: {'lep_pt': e.leptons_pt,'lep_eta': e.leptons_eta,}")
    .AsAwkwardArray()
).values()

I end up with the error:

Failed to transform input file root://eosatlas.cern.ch//eos/atlas/atlascerngroupdisk/phys-higgs/HSG8/tH_v34_minintuples_v0/mc16a_nom/410470_AFII_user.vvecchio.27456668._000001.output.root: file not found ([ERROR] Server responded with an error: [3010] Unable to give access - user access restricted - unauthorized identity used ; Permission denied )

and if I try to open the file just using a coffea DaskExecutor I use:

from distributed import Client
import dask
cl = Client("tls://mohamed-2ealy-40cern-2ech.dask.casa.af.uchicago.edu:8786")
with dask.config.set(scheduler='processes', num_workers=5):
    dask_run = processor.Runner(
        executor = processor.DaskExecutor(client=cl),
        schema=BaseSchema,
    )

    coffea_out = dask_run(
        {'data': file},
        "nominal_Loose",
        processor_instance=MyProcessor(),
    )

and I get the following error (same as the one above):

FileNotFoundError: file not found ([ERROR] Server responded with an error: [3010] Unable to give access - user access restricted - un-authorized identity used ; Permission denied
)

It seems like others are able to access this file just fine (see the thread on servicex channel). Other notable mentions of problems that may be related are that voms-proxy-init does not work for me on the AF (I get a SegFault) and I also cannot run xdrcp ( I get Run: [ERROR] Operation is not implemented: (source) when I run xrdcp -f root://192.170.240.18:1094//root://eosuser.cern.ch//eos/atlas/atlascerngroupdisk/phys-higgs/HSG8/tH_v34_minintuples_v0/mc16a_nom/410470_AFII_user.vvecchio.27456668._000001.output.root /dev/null )

Any ideas on what is happening or could be done?
