No Failover works, Failover does not work

I'm am trying to implement a failover solution for dhcp to replace a current
NT solution which does not support failover. I have upgraded to the 3.0.4,
but when the systems are configured for failover, I get no leases, when the
systems are not configured for failover each server works as expected. We
are using cisco routers and the helper-addresses are configured correctly,
and work without the failover configured.
Primary Config:
-----------------------
failover peer "dhcp-failover" {
primary; # declare this to be the primary server
address 10.153.100.26;
port 520;
peer address 10.153.100.27;
peer port 520;
max-response-delay 30;
max-unacked-updates 30;
load balance max seconds 3;
mclt 1800;
split 128;
}
include "/etc/dhcpd.pools";
Secondary Config:
----------------------------
failover peer "dhcp-failover" {
Secondary; # declare this to be the secondary server
address 10.153.100.27;
port 520;
peer address 10.153.100.26;
peer port 520;
max-response-delay 30;
max-unacked-updates 30;
load balance max seconds 3;
mclt 1800;
}
include "/etc/dhcpd.pools";
The common pool file:
---------------------------------
authoritative;
ddns-update-style none;
option domain-name "corp.idt.net";
option domain-name-servers 172.16.202.100, 172.16.202.101;
option netbios-name-servers 10.153.100.17, 169.132.10.4;
option ntp-servers 10.153.100.17;
option Call_Server_Information code 128 = text;
option VLAN_Information code 191 = text;
subnet 10.153.100.0 netmask 255.255.255.0 {
# this is the subnet the machines actually sits on
}
# 2nd Floor VLAN
subnet 10.153.22.0 netmask 255.255.255.0 {
option subnet-mask 255.255.255.0;
option broadcast-address 10.153.22.255;
option routers 10.153.22.1;
pool {
failover peer "dhcp-failover";
deny dynamic bootp clients;
max-lease-time 28800; # 30 minutes
range 10.153.22.3 10.153.22.229;
}
}
I cannot find any relevant failure messages in the log and the lease file
doesn't show any leases.
Anyone see a mistake in my config? Thank you.
