allow_daemons_dump_core doesn't work?

[Chuck Anderson <cra WPI EDU>]

I've been having issues with BIND so I set up the named process to 
dump core and enabled allow_daemons_dump_core.  However, it would not 
create any core file until I put SELinux into permissive mode.  I also 
didn't get any audit messages related to the failed core dump.  Why is 
that?  The CWD of the process is /var/named which is where the core 
dump got written after I put SELinux in permissive mode.
