like i did: i have the key in /etc/dhcpd.conf

here a snipplet of my dhcpd.conf:

allow unknown-clients;

subnet [network] netmask 255.0.0.0 {
        ddns-updates on;
        ddns-domainname "[domainname]";
        ddns-rev-domainname "in-addr.arpa";
        option domain-name "domainname";
        option domain-name-servers [dns1], [dns2];
        option routers [default gateway];
        range [from] [to];
        allow unknown-clients;
        allow client-updates;
        authoritative;
        }

ddns-update-style interim;

key DHCP_UPDATER {
        algorithm hmac-md5;
        secret [encrypted_secret];
}

zone mydomain.tld. {
        primary 127.0.0.1;
        key DHCP_UPDATER;
}

zone 0.0.10.in-addr.arpa. {
        primary 127.0.0.1;
        key DHCP_UPDATER;
}

this key is also mentionned in named.conf (by zone):

include "/etc/dhcpd.key";

zone "mydomain.tld" IN {
        type master;
        file "zone.db";
        allow-update { key DHCP_UPDATER; };
};


and thus, i have /etc/dhcpd.key:

key DHCP_UPDATER {
        algorithm hmac-md5;
        secret [encrypted secret];
};
