[Unbound-users] Failure of include file Unbound 1.4.22

[zongo saiba]

Greetings to all,

I have an include statement in my unbound config file that is not
accepted on a Debian machine. the error message:
error parsing local-data / could not parse the RR's class / Bad
local-data RR 'adsitename'\ A 127.0.0.1
Could not set up local zones
The same include statement on a Ubuntu machine works.
Could anyone please help me understand why this is not working on a
Debian box ?

Kind Regards,

zongo
