Serveur BIND de Centos : Impossible de démarrer le démon nommé

J'ai installé un nouveau serveur Centos et y ai installé bind et bind-utils. Le contenu de /etc/named.conf est :

# create new
 options {
    directory "/var/named";
    allow-query { localhost; 10.1.2.0/24; };
    allow-transfer { localhost; 10.1.2.0/24; };
    recursion yes;
};
controls {
    inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
view "internal" {
    match-clients {
        localhost;
        10.1.2.0/24;
    };
    zone "." IN {
        type hint;
        file "named.ca";
    };
    zone "amadeus.netvision" IN {
        type master;
        file "amadeus.netvision.lan";
        allow-update { none; };
    };
    zone "0.0.10.in-addr.arpa" IN {
        type master;
        file "0.0.10.db";
        allow-update { none; };
    };
    zone "localdomain" IN {
        type master;
        file "localdomain.zone";
        allow-update { none; };
    };
    zone "localhost" IN {
        type master;
        file "localhost.zone";
        allow-update { none; };
    };
    zone "0.0.127.in-addr.arpa" IN {
        type master;
        file "named.local";
        allow-update { none; };
    };
    zone "255.in-addr.arpa" IN {
        type master;
        file "named.broadcast";
        allow-update { none; };
    };
    zone "0.in-addr.arpa" IN {
        type master;
        file "named.zero";
        allow-update { none; };
    };
};
view "external" {
    match-clients { any; };
    allow-query { any; };
    recursion no;
    zone "amadeus.netvision" IN {
        type master;
        file "amadeus.netvision.wan";
        allow-update { none; };
    };
};
include "/etc/rndc.key";

# allow-query  query range you permit
# allow-transfer  the range you permit to transfer zone info
# recursion  allow or not to search recursively
# view "internal" { *** };  write for internal definition
# view "external" { *** };  write for external definition
# For How to write for reverse resolving, Write network address reversely like below.
# 10.1.2.0/24
# network address 10.1.2.0
# range of network 10.1.2.0 - 10.0.0.255
# how to write 0.0.10.in-addr.arpa
# 172.16.0.80/29
# network address 172.16.0.80
# range of network 172.16.0.80 - 172.16.0.87
# how to write 80.0.16.172.in-addr.arpa

Lorsque j'essaie de lancer le démon nommé, j'obtiens l'erreur suivante :

[root@srv ~]# service named restart
Stopping named:                                            [  OK  ]
Starting named: 
Error in named configuration:
/etc/named.conf:9: unknown key 'rndckey'
                                                           [FAILED]
[root@srv ~]#

Je ne comprends pas ce que je fais mal, j'ai créé le rndc.key en utilisant la commande suivante : rndc-confgen -a -c /etc/rndc.key et il a créé la clé mais j'ai toujours la même erreur. Le fichier est présent dans le chemin correct : /etc/rndc.key et c'est inclus dans le /etc/named.conf fichier.
