DDNS, KEY and SIG entry

[hschlecht]

I have an AIX 4.3.2.6 server on which work a DDNS and DHCP server. Through
the automatic update function, each time that the DHCP server lease an IP
address, a nsupdate through the dhcpaction script is carried out. This allow
the creation  of an A and PTR entry in the zone and teverse zone. But as I
can see it, an KEY and SIG entry is also automatically created in the zone
files.

Is it possible to make that these two entry are not automatically created ?

The update command in the dhcp configuration file is :

updateDNS "/usr/sbin/dhcpaction %s %s %s %s BOTH NONIM"

The zone configuration in the named.conf file is :

zone "dtv.stb.energy.abc.com" {
 type master;
 file "dtv.stb.energy.abc.com.db";
# check-names fail;
 allow-update {localhost;};
 update-security unsecured;
};


Thank for your help.
