-This is the INSTALL file for 0.4. See
-http://www.venaas.no/ldap/bind-sdb/ for updates or other information.
-
-BUILDING
-
-You need the source for BIND 9.1.0 or newer (for zone transfers you
-will need at least 9.1.1rc3 due to a bug). Basically you need to follow
-the instructions in doc/misc/sdb, if my instructions doesn't make sense,
-please have a look at that as well.
-
-Copy ldapdb.c to bin/named and ldapdb.h to bin/named/include in the
-source tree.
-
-Next alter bin/named/Makefile.in. Add ldapdb.@O@ to DBDRIVER_OBJS and
-ldapdb.c to DBDRIVER_SRCS. You also need to add something like
--I/usr/local/include to DBDRIVER_INCLUDES and
--L/usr/local/lib -lldap -llber -lresolv to DBDRIVER_LIBS
-depending on what LDAP library you have and where you installed it.
-
-Finally you need to edit bin/named/main.c. Below where it says
-"#include "xxdb.h"", add the line "#include <ldapdb.h>". Below where
-it says "xxdb_init();" add the line "ldapdb_init();", and finally
-below where it says "xxdb_clear();", add "ldapdb_clear();".
-
-Now you should hopefully be able to build it.
-
-
-CONFIGURING
-
-Before you do any configuring of LDAP stuff, please try to configure
-and start bind as usual to see if things work.
-
-To do anything useful, you need to store a zone in some LDAP server.
-From this release on, you must use a schema called dNSZone. Note that
-it relies on some attribute definitions in the Cosine schema, so that
-must be included as well. The Cosine schema probably comes with your
-LDAP server. You can find dNSZone and further details on how to store
-the data in your LDAP server at
-http://www.venaas.no/ldap/bind-sdb/
-
-For an example, have a look at my venaas.com zone. Try a subtree search
-for objectClass=* at
-ldap ldap://129.241.20.67/dc=venaas,dc=com,o=DNS,dc=venaas,dc=no
-
-To use it with BIND, I've added the following to named.conf:
-zone "venaas.com" {
- type master;
- database "ldap ldap://129.241.20.67/dc=venaas,dc=com,o=DNS,dc=venaas,dc=no 172800";
-};
-
-When doing lookups BIND will do a sub-tree search below the base in the
-URL. The number 172800 is the TTL which will be used for all entries that
-haven't got the dNSTTL attribute.
-
-Stig Venaas <venaas@uninett.no> 2001-04-12
+++ /dev/null
-This is an attempt at an LDAP back-end for BIND 9 using the new simplified
-database interface "sdb". This is the fifth release (0.5) and is not ready
-for production use yet. Note that this version (and 0.4) uses a new schema
-and is not backwards compatible with versions before 0.4. The big changes in
-0.5 are thread support and improved connection handling. Multiple threads
-can now access the back-end simultaneously, and rather than having one
-connection per zone, there is now one connection per thread per LDAP server.
-This should help people with multiple CPUs and people with a huge number of
-zones. One final change is support for literal IPv6 addresses in LDAP URLs.
-At least OpenLDAP 2 has IPv6 support, so if you use OpenLDAP 2 libraries and
-server, you got all you need.
-
-If you have bug reports, fixes, comments, questions or whatever, please
-contact me. See also http://www.venaas.no/ldap/bind-sdb/ for information.
-
-See INSTALL for how to build, install and use.

-.TH zone2ldap 1 "8 March 2001"
-.SH NAME
-zone2ldap /- Load BIND 9 Zone files into LDAP Directory
-.SH SYNOPSIS
-zone2ldap [-D Bind DN] [-w Bind Password] [-b Base DN] [-z Zone] [-f Zone File ] [-h Ldap Host] [-cd] [-v]
-.SH DESCRIPTION
-zone2ldap will parse a complete BIND 9 format DNS zone file, and load
-the contents into an LDAP directory, for use with the LDAP sdb back-end.
-
-If the zone already exists, zone2ldap will exit succesfully. If the zone does not exists, or
-partially exists, zone2ldap will attempt to add all/missing zone data.
-
-.SS Options
-.TP
--b
-LDAP Base DN. LDAP systems require a "base dn", which is generally considered the LDAP Directory root.
-If the zone you are loading is different from the base, then you will need to tell zone2ldap what your LDAP
-base is.
-.TP
--v
-Print version information, and immediatly exit.
-.TP
--f
-Zone file. Bind 9.1 compatible zone file, from which zone information will be read.
-.TP
--d
-Dump debug information to standard out.
-.TP
--w
-LDAP Bind password, corresponding the the value of "-b".
-.TP
--h
-LDAP Directory host. This is the hostname of the LDAP system you wish to store zone information on.
-An LDAP server should be listening on port 389 of the target system. This may be ommited, and will default
-to "localhost".
-.TP
--c
-This will create the zone portion of the DN you are importing. For instance, if you are creating a domain.com zone,
-zone2ldap should first create "dc=domain,dc=com". This is useful if you are creating multiple domains.
-.TP
--z
-This is the name of the zone specified in the SOA record.
-.SH EXAMPLES
-Following are brief examples of how to import a zone file into your LDAP DIT.
-.SS Loading zone domain.com, with an LDAP Base DN of dc=domain,dc=com
-zone2ldap -D dc=root -w secret -h localhost -z domain.com -f domain.com.zone
-
-This will add Resource Records into an ALREADY EXISTING dc=domain,dc=com. The final SOA DN in this case, will be
-dc=@,dc=domain,dc=com
-
-.SS Loading customer.com, if your LDAP Base DN is dc=provider,dc=net.
-zone2ldap -D dc=root -w secret -h localhost -z customer.com -b dc=provider,dc=net -f customer.com.zone -c
-
-This will create dc=customer,dc=com under dc=provider,dc=net, and add all necessary Resource Records. The final
-root DN to the SOA will be dc=@,dc=customer,dc=com,dc=provider,dc=net.

-#
-# Sample lookup procedure for tcldb
-#
-# This lookup procedure defines zones with identical SOA, NS, and MX
-# records at the apex and a single A record that varies from zone to
-# zone at the name "www".
-#
-# Something like this could be used by a web hosting company to serve
-# a number of domains without needing to create a separate master file
-# for each domain. Instead, all per-zone data (in this case, a single
-# IP address) specified in the named.conf file like this:
-#
-# zone "a.com." { type master; database "tcl 10.0.0.42"; };
-# zone "b.com." { type master; database "tcl 10.0.0.99"; };
-#
-# Since the tcldb driver doesn't support zone transfers, there should
-# be at least two identically configured master servers. In the
-# example below, they are assumed to be called ns1.isp.nil and
-# ns2.isp.nil.
-#
-
-proc lookup {zone name} {
- global dbargs
- switch -- $name {
- @ { return [list \
- {SOA 86400 "ns1.isp.nil. hostmaster.isp.nil. \
- 1 3600 1800 1814400 3600"} \
- {NS 86400 "ns1.isp.nil."} \
- {NS 86400 "ns2.isp.nil."} \
- {MX 86400 "10 mail.isp.nil."} ] }
- www { return [list [list A 3600 $dbargs($zone)] ] }
- }
