If you are running a release prior to 1.17, you need to use the old name
iprop_slave_poll.  (The old name still works in 1.17 as well.)

Also make sure to set the value on the machine running kpropd (not the
master KDC where kadmind is run), and to restart kpropd.

I don't think the delta time format supports floating point values, but
"1s" or just "1" should work.

Polling every second will cause a little bit of work on the replica and
the master KDC each second, and use a little bit of network traffic.
With today's computers and networks it's probably going to have much impact.
