It means that something is trying to use dnssec when querying the
dnsserver, Samba at this time knows nothing about dnssec and 'IsSigned'
isn't in the list it checks against, hence the message you are getting.
It looks like Samba needs an update in this area, if only to stop that
message.

I wouldn't say 'forgotten', more ignored because a bug hasn't been
opened and it is a very minor problem.
