This directory contains a slapd overlay, smbk5pwd, that extends the
PasswordModify Extended Operation to update Kerberos keys and Samba
password hashes for an LDAP user.

The Kerberos support is written for Heimdal using its hdb-ldap backend.
If a PasswordModify is performed on an entry that has the krb5KDCEntry
objectclass, then the krb5Key and krb5KeyVersionNumber will be updated
using the new password in the PasswordModify request.

The Samba support is written using the Samba 3.0 LDAP schema. If a
PasswordModify is performed on an entry that has the sambaSamAccount
objectclass, then the sambaLMPassword, sambaNTPassword, and sambaPwdLastSet
attributes will be updated accordingly.

To use the overlay, add:

	include <path to>/krb5-kdc.schema
	include <path to>/samba.schema

	moduleload <path to>smbk5pwd.so
	...

	database bdb
	...
	overlay smbk5pwd

to your slapd configuration file. (You should obtain the necessary schema
files from the Heimdal and/or Samba distributions. At this time, there
are several known errors in these schema files that you will have to
correct before they will load in slapd.)

The provided Makefile builds both Kerberos and Samba support by default.
You must edit the Makefile to insure that the correct include and library
paths are used. You can change the DEFS macro if you only want one or the
other of Kerberos or Samba support.

This overlay is only set up to be built as a dynamically loaded module.
If you need to build it statically, you will have to move it into the
slapd/overlays directory and edit the Makefile and overlays.c to reference
it. You will also have to define SLAPD_OVER_SMBK5PWD to SLAPD_MOD_STATIC,
and add the relevant libraries to the main slapd link command.
