You seem to have muddled up dnssec-enable and dnssec-validation.
The default is "dnssec-enable yes". This enables support for the DO bit
and correct RRSIG handling. It's usually best to omit the dnssec-enable
option from your configuration file.
The dnssec-validation option controls validation. The default is "no".
If you set it to "yes" then you need to manually configure your trust
anchors. If you set it to "auto" then you can omit any managed-keys
configuration, and BIND will use its built-in defatult. It's usually
best to set "dnssec-validation auto".
A managed-keys clause without an initial key would be empty :-)

rough, occasionally very rough later. Occasional rain. Good, occasionally
