Hmm, further testing revealed that patch 203 changed behavior little bit: 
Zones were loaded from LDAP correctly, but the SOA serial wasn't changed at 
all. As a result, zone transfers return inconsistent results if the data in 
LDAP are changed when BIND was not running.

Patch 203-v2 imitates the old behavior from bind-dyndb-ldap 3.x: Zone serial 
is bumped *once* for each zone, so any changed in LDAP will be transferred 
correctly (with new serial).
