[Kea-users] DDNS remains off - DDNS: disabled

Hi there!

do I need something else to enable DDNS? The log shows "DDNS: disabled". 
"ddns-send-updates" have to be used - 
https://readthedocs.org/projects/kea/downloads/pdf/latest/ table 8 p. 
138 lists "ddns-send-update" (without "s") - using the version w/o "s" 
results in complaints in the log. Is this a feature?
