[Kea-users] migrating from DHCPd to Kea

[Peter Davies]

Hi Brendan,
    Kea will not be able to grant leases if it cannot contact its lease 
database.
Your configuration file and logging would be helpful.

Also, setting  the "authoritative" to true will force Kea to always 
reject INIT-REBOOT requests from unknown clients
