hint zone conflicts with allow-query statement !

[Eric Belhomme]

Hi, I'm in trouble with a bind9.2.4 server running on Debian Sarge server 
:


acl "acl_cache_clients" { 127.0.0.0/8; localnet; };

zone "." {
        type hint;
        file "/etc/bind/db.root";
        allow-query { "acl_cache_clients"; };
};

and there is my logs :
Jan 26 10:28:06 titou named[12721]: starting BIND 9.2.4 -u bind
Jan 26 10:28:06 titou named[12721]: using 2 CPUs
Jan 26 10:28:06 titou named[12721]: loading configuration from 
'/etc/bind/named.conf'
Jan 26 10:28:06 titou named[12721]: /etc/bind/named.conf:19: option 
'allow-query' is not allowed in 'hint' zone '.'
Jan 26 10:28:06 titou named[12721]: loading configuration: failure
Jan 26 10:28:06 titou named[12721]: exiting (due to fatal error)


I have another bind9 running on another Debian Sarge server, and it works 
well with same config for the hint zone !!!
So what could go wrong with my config ???

Regards,
