Authozied Answers While using Transparent-Cache

Hi I would like to know, is there a way to achieve authorized answers while using transparent-dns cache in GTM ? I have prepared a lab and there is a couple of domain name servers that working as authorized name servers for five domains. When I send a query to the listener, they reply as expected in authorized manner. But after define a transparent-cache profile on the listener definition, I always get non-authorized answers for those same 5 domains. What am I missing ?
