[sonjaya@stud.che.itb.ac.id]

dear all
i try follow this manual :
http://www.sbfsbo.com/mike/OpenldapTutorial/#ldapadd

and here my slapd.conf
# $OpenLDAP: pkg/ldap/servers/slapd/slapd.conf,v 1.23.2.8 2003/05/24
23:19:14 ku
#
# See slapd.conf(5) for details on configuration options.
# This file should NOT be world readable.
#
include         /usr/local/openldap/etc/openldap/schema/core.schema

# Define global ACLs to disable default read access.

# Do not enable referrals until AFTER you have a working directory
# service AND an understanding of referrals.
#referral       ldap://root.openldap.org

pidfile         /usr/local/openldap/var/slapd.pid
argsfile        /usr/local/openldap/var/slapd.args

# Load dynamic backend modules:
# modulepath    /usr/local/openldap/libexec/openldap
# moduleload    back_bdb.la
# moduleload    back_ldap.la
# moduleload    back_ldbm.la
# moduleload    back_passwd.la
# moduleload    back_shell.la

# Sample security restrictions
#       Require integrity protection (prevent hijacking)
#       Require 112-bit (3DES or better) encryption for updates
#       Require 63-bit encryption for simple bind
# security ssf=1 update_ssf=112 simple_bind=64

# Sample access control policy:
#       Root DSE: allow anyone to read it
#       Subschema (sub)entry DSE: allow anyone to read it
#       Other DSEs:
#               Allow self write access
#               Allow authenticated users read access
#               Allow anonymous users to authenticate
#       Directives needed to implement policy:
# access to dn.base="" by * read
# access to dn.base="cn=Subschema" by * read
# access to *
#       by self write
#       by users read
#       by anonymous auth
#
# if no access controls are present, the default policy is:
#       Allow read by all
#
# rootdn can always write!
