Hello all,
I'm not sure if this is the right place to raise this question but maybe
you can help.
Our site is currently switching batch system from PBS/Torque to SGE, and
we're testing the middleware a separate test-cluster. Everything is
working fine, except CMS jobs. As you may know, CMS jobs use ROOT
(http://root.cern.ch/drupal/) for their computational and data management
purposes. The problem occurs right after the job starts on the WN, and
want to open the ROOT RFIO file. This is the error output of a failing
job:

I'm not sure what can cause this error. I double checked the DPM commands,
everything is working fine: dpns-*, rfcp, globus-url-copy, and srmcp.
Do you have any idea what this 'Could not load
security mechanism' might be?
Thanks in advance!
Best regards,
Benjamin
