[Kea-users] Depreciated kea-ctrl-agent Required For HA - What The...

Hi All,

In the latest stable version of Kea ARM (v3.0.1) it says (p59):

~~~

The kea-ctrl-agent is deprecated. As of Kea 2.7.2 the Kea servers: 
kea-dhcp4, kea-dhcp6, and kea-dhcp-ddns directly support command API 
connections over HTTPS/HTTP.

~~~

However, I get the impression from Section 17.12 libdhcp_ha.so 
(p418-456), particularly the sample configuration on p421-423, and 
Section 17.12.14 Control Agent Configuration (p440-441), that 
kea-ctrl-agent *is* required.

So my question is: Which is the case: Is kea-ctrl-agent required for HA, 
or is kea-ctrl-agent depreciated and thus *not* required for HA; or is 
kea-ctrl-agent *both* depreciated *and* required for HA, in which case 
"Wha ?!?!" and what are we supposed to do (assuming we want to use HA 
but not depreciated modules)?

Thanks in advance
