When putty into Linux server a kerberos ticket is obtained and the environment variable "KRB5CCNAME" is set and Job ran successfully.
KRB5CCNAME=FILE:/tmp/krb5cc_<uid>_<random 6 char>
But when jobs are run via Autosys, the ticket is obtained to the same location above but the environment variable "KRB5CCNAME" is not set.
So, Kerberos then looks at the default ticket cache location and jobs fail.
