Verify EOS access via certificate

Check authentification with EOS

To be sure that everything is working fine with certificate one can check it via following commands

$ export EOS_MGM_URL=root://eos.jinr.ru
$ eos -b whoami
Virtual Identity: uid=18401 (18401) gid=530 (530) [authz:gsi] host=gril78.jinr.ru domain=jinr.ru geo-location=RU::JINR::LIT

One can see in output that user is authentificated with uid=18401 via GSI (x509 certificate) authentification [authz:gsi]

In case one see following message

Virtual Identity: uid=99 (99) gid=99 (99) [authz:unix] host=gril78.jinr.ru domain=jinr.ru geo-location=RU::JINR::LIT

that means that user is NOT authentificated. It is authentificated as nobody (uid=99).

Open file from EOS via certificate

$ source /cvmfs/nica.jinr.ru/sw/os/login.sh
$ module add mpdroot
