In order to understand SELinux more I enabled SELinux on my system. I noticed a
problem with access denied on portmap and ntpdate and ntpd services. The following is
the relevent information snipped from the dmesg output:

Since I use ntpdate to keep my system date and time in sync this is a
problem. I don't know what not having portmap runnin will do.
Does anyone know why I am being denied access to these services. If so is there
a way to correct this denial?
