You should have powers to login (from within CERN). I have opened up the directory with corefile etc /var/spool/abrt/ccpp-2016-03-09-17:29:32-921/ (this is a repeat crash, the backtrace of the most recent one corresponds still to the "old" corefile). I confirm that the 'xrootd' user should have no powers to use the machine keytab, nor would it have a Kerberos ticket cache. I suspect that Kerberos is invoked via some fallthrough authentication sequence, after something else (unix? the machine is whitelisted in EOS) failed. --- You are receiving this because you are subscribed to this thread.
