Dear experts,
I write in this forum because the CERN Service Desk redirected me here.
I am trying to launch in batch my analysis, which is a ROOT macro
taking flat ntuples as input. The input ntuples are located in a Tier
2 GRID. Here an example of the input file path:
root://node12.datagrid.cea.fr//cms/triv … 1_n2A.root
when I launch my analysis in interactive mode from an lxplus machine
(on a small fraction of the input files,as a test), I am asked to put
my PEM password and everything works.
The size of all the input files is too big to run them interactively.
When I try to launch the same analysis in batch the jobs crash with
the following error:

Thread 3 (Thread 0x2b6ed13b0940 (LWP 23954)):
My guess is that this is due to a problem with the authentication.
How can I solve this problem? Is there a way to access these files on
a storage element through the batch system?
Thank you
Best Regards
