That is the documentation for the current ntp-dev release.
Please use the documentation shipped with your version of NTP or the
documentation archived at http://doc.ntp.org/4.2.4

5 is the default orphan stratum. Use at least that (i.e. >= 5).

The current stable release is NTP-4.2.6p3 and you are using NTP-4.2.4p7.
On the surface it does not look like there's much difference between
these two versions. But there is; substantial changes were made in the
4.2.5* development series.
Here's how you should be reading these versions:
NTP-4.2.4p7 == NTP-4 v2.4.7
NTP-4.2.6p3 == NTP-4 v2.6.3
If you want to use Orphan Mode you should upgrade to the current stable
