This is probably because you once disabled the dontaudit statements (using "semodule -DB" or so). By default, these are dontaudit'ed because they are always triggered on domain transitions, but hardly needed (some exceptions notwithstanding). Run "semodule -B" to re-enable the dontaudit statements again.

Ouch right, after that and rebooting I'm no longer seeing the denials. Thanks, I was suspecting some sort of PEBKAC when reporting this. ;-)
