1) su command is not failing
2) cat is working as expected

su -c creates new process in RHEL-5 - which is expected behaviour as it
could cause security problems. This process has apparently no
controlling terminal /dev/tty. There was non-upstream longoption
--session-command added in RHEL-5 to restore RHEL-4 behaviour. Consider
using it in this case.

Next time it would be better to use RHEL product support or RedHat
bugzilla. Please try to use it instead of upstream mailing list, if
--session-command is not solving your issue.
