3434. [bug] Pass client info to the DLZ findzone() entry
point in addition to lookup(). This makes it
possible for a database to answer differently
whether it's authoritative for a name depending
on the address of the client. [RT #31775]
3432. [func] Multiple DLZ databases can now be configured.
DLZ databases are searched in the order configured,
unless set to "search no", in which case a
zone can be configured to be retrieved from a
particular DLZ database by using a "dlz <name>"
option in the zone statement. DLZ databases can
support type "master" and "redirect" zones.
[RT #27597]
- multiple DLZ's can be specified, including multiple DLZ's using
the same driver; e.g., two different back-ends both loaded by the
dlopen driver
- new "search" option can be specified in a DLZ indicating whether
this DLZ database should be searched for unknown zones. The
default is "yes". If "no", then the zone can only be found by
named if it's registered in the zone table, which happens if the
zone is configured for dynamic updates, or if "dlz <dlzname>" is
specified in the zone statement. (The latter functionality is
incomplete in this commit).

2988. [experimental] Added a "dlopen" DLZ driver, allowing the creation
of external DLZ drivers that can be loaded as
shared objects at runtime rather than linked with
named. Currently this is switched on via a
compile-time option, "configure --with-dlz-dlopen".
Note: the syntax for configuring DLZ zones
is likely to be refined in future releases.

2987. [func] Improve ease of configuring TKEY/GSS updates by
adding a "tkey-gssapi-keytab" option. If set,
updates will be allowed with any key matching
a principal in the specified keytab file.
"tkey-gssapi-credential" is no longer required
and is expected to be deprecated. (Contributed
