Hi and thanks Jim for your response.

I think so too. This is the unique reason for what the server cannot 
validate the signature... but I use the private key of the server for 
signing the request and the server knows its own key.

Also, I've added a trusted-keys tag in the file /etc/named.conf where I 
specify the public key of the server to do the validation.

Thanks a lot!!
