Hi,In our website, we use HTCondor as our job submission system. We use Drupal for our site and an Apache server.Recently we upgraded our server from RHEL6 to RHEL7 and I installed the newest stable version of HTCondor (8.4.5 from 8.0.6). When submitting jobs through the terminal, everything works correctly. However, when letting Drupal submit the jobs (as the Apache user), I get this error:04/01/16 10:29:23 (pid:21220) authenticate_self_gss: acquiring self credentials failed. Please check your Condor configuration file if this is a server process. Or the user environment variable if this is a user process.GSS Major Status: General failureGSS Minor Status Error Chain:globus_gsi_gssapi: Error with GSI credentialglobus_gsi_gssapi: Error with gss credential handleglobus_credential: Valid credentials could not be found in any of the possible locations specified by the credential search order.Valid credentials could not be found in any of the possible locations specified by the credential search order.Attempt 1globus_credential: Error reading host credentialglobus_sysconfig: Could not find a valid certificate file: The host cert could not be found in:1) env. var.
