Offhand, the only problem I see in your config is that you've declared
'mclt' in both the primary and secondary configs.  The 'dhcpd.conf' man
page says you're only supposed to do that on the primary (at least on
3.0.3, which is what we're using.)

I'd expect that you'd see some sort of error message in the logs,
though; its surprising that the servers just sit there and don't issue
