Without the -R switch only the directory itself will be labeled. I'm
pretty sure you want to run restorecon as suggested by dwalsh.

What does 'ausearch -m -ts recent' tell? You can pipe the output to
audit2why or audit2allow like:

ausearch -m avc -ts recent | audit2why
ausearch -m avc -ts recent | audit2allow -M mysnmp

The latter will generate a loadable module. There is some documentation
at [1] about creating and loading your own modules.
