simple: how to add hosts for higher domain ?

[Uwe Dippel]

I may be slow, but I've been playing for several days with this problem:

When I put

zone "uniten.edu.my" in named.conf, I can - correctly - add 
helper.uniten.edu.my to the file ../master/uni.sec; A, MX and everything.
And it will even resolve properly.
But this is outright wrong, since my bind is no SOA for uniten.edu.my; 
and messes up a few things.

But when I (correctly) put
zone "dns2.uniten.edu.my" in named.conf, all records in 
../master/uni.sec will show up as .....dns2.uniten.edu.my; including 
that helper; which will - wrongly - make it as helper.dns2.uniten.edu.my.

Now I'm asking for a hint, how to bring both together; how could a 
machine contain a name for another box having the same hierarchy as the 
bind machine ?
How can I make dns2.uniten.edu.my resolve helper.uniten.edu.my properly ?

I bet, this has been answered a few times; and so I'd ask for a hint, 
where to find this. I simply had no intelligent keywords for google here.

Thanks in advance,

Uwe
