Thanks a lot. I've got a web interface for editing DNS entries. It uses
this schema. I think editing the database by hand is also easier and
the schema is more LDAP-friendly.

Uh. This is very bad news. It forces to make a redundancy in the database.
The same information is placed in DN and the associatedDomain. It is
annoying if it is edited by hand with LDAP browser.
But I don't understand exactly. In my code everyting was working. I could
even do a transfer to secondary DNS which was powered by BIND.

Just now I'm on vacation :) but I'll do it.

Could AXFR without assosiatedDomain be an option?
