Adding the check for the presence of the SOA record is a good idea and I 
already sent a patch to Bert, but it won't solve your problem. If you add a 
zone "1.168.192.in-addr.arpa" below "168.192.in-addr.arpa" in your LDAP 
directory as subtree, AXFR transfers of "168.192.in-addr.arpa" will still 
include those records from "1.168.192.in-addr.arpa".

The only solution is to use "simple" mode and store "1.168.192.in-addr.arpa" 
at the same level as "168.192.in-addr.arpa" in the LDAP tree.
