Hi.

When I use bind-dyndb-ldap plugin with this patch, named
does not start due to:

rbt.c:1379: REQUIRE(name->buffer != ((void *)0)) failed, back trace

It looks like you should use INIT_BUFFERED_NAME(name); used in the
original code instead of dns_name_init(&name, NULL). The macro
initializes the buffer in "name", which is missing in the new code.
