Description of problem:

When aureport is run from a file in /etc/cron.hourly or /etc/cron.daily, it uses
standard input for input rather than /var/log/audit/audit.log.  It finds no log
records on standard input.


Version-Release number of selected component (if applicable):
audit-1.6.2-4.fc8

How reproducible:
every time

Steps to Reproduce:
1.Create a file in /etc/cron.daily or /etc/cron.hourly to run aureport
2.Wait for cron to run the file
3.
  
Actual results:
No data is seen by aureport

Expected results:
aureport processes the data in /var/log/audit/audit.log

Additional info:

The following check is done in aureport.c:

        if (input_is_pipe())
                rc = process_stdin();
        else if (user_file)
                rc = process_file(user_file);
        else
                rc = process_logs(&config);

When a job is run by cron, standard input is set to a pipe so the pipe is used
ranther than the files, even if the -if option is given on the aureport command.
