LDAP Won't start

[Pilot <pilot@ekynoxe.com>]

Hi, I need to install ldap for a project for my school, and after all 
the installation process, executing the following command fails to start 
 slapd :

# /etc/init.d/ldap start
Vérification des fichiers de configuration pour  :config file testing 
succeeded
Démarrage de slapd :                                       [ÉCHOUÉ]

here are my slapd.conf and ldap.conf :

***********************************************************************************

# See slapd.conf(6) for details on configuration options.
# This file should NOT be world readable.

# 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.

# 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
# allows anyone and everyone to read anything but restricts
# updates to rootdn.  (e.g., "access to * by * read")
#
# rootdn can always read and write EVERYTHING!
