In that case you need to do one of the following:

a) turn selinux off or
b) set selinux to permissive or
c) configure selinux to allow what you're trying to do - read up on
"audit2allow". It's behaviour varies with OS release (eg RHEL4 is very
different to RHEL5) so I can't give you instructions without knowing
your OS.
