Nous installons les paquets pré requis
# aptitude install apt-transport-https gnupg2 curl
Nous créons le fichier du dépôt LTB
# vi /etc/apt/sources.list.d/ltb-project.list
et ajoutons ces lignes
## # LTB project repository # version: Bullseye ## deb [arch=amd64 signed-by=/usr/share/keyrings/ltb-project-openldap-archive-keyring.gpg] https://ltb-project.org/debian/openldap25/bullseye bullseye main
Nous importons la clé GPG du dépôt
# curl https://ltb-project.org/documentation/_static/RPM-GPG-KEY-LTB-project | gpg --dearmor > /usr/share/keyrings/ltb-project-openldap-archive-keyring.gpg
Nous installons le paquet
# aptitude update && install openldap-ltb openldap-ltb-contrib-overlays openldap-ltb-mdb-utils
Par défaut, OpenLDAP LTB utilise le fichier slapd.conf. Nous allons plutôt utiliser la méthode cn=config pour stocker la configuration
Nous stoppons le service
sudo systemctl stop slapd-ltb
Nous “salons” notre mot de passe Manager
sudo /usr/local/openldap/sbin/slappasswd
Il vous est demandé de saisir deux fois votre mot de passe, et le mot de passe “salé” sera généré (exemple avec le mot de passe “secret”
New password:
Re-enter new password:

Nous adaptons le fichier slapd.conf
sudo vi /usr/local/openldap/etc/openldap/slapd.conf

# 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!

Nous créons le répertoire qui accueillera la configuration
sudo mkdir -v /usr/local/openldap/etc/openldap/slapd.d/
Nous copions la configuration
sudo /usr/local/openldap/sbin/slaptest -f /usr/local/openldap/etc/openldap/slapd.conf -F /usr/local/openldap/etc/openldap/slapd.d -d 256
Nous mettons les droits sur le répertoire
sudo chown -R ldap.ldap /usr/local/openldap/etc/openldap/slapd.d
Nous adaptons le paramètre “SLAPD_CONF_DIR” dans le fichier /usr/local/openldap/etc/openldap/slapd-cli.conf
SLAPD_CONF_DIR="$SLAPD_PATH/etc/openldap/slapd.d"
Nous démarrons le service
sudo service slapd start
Nous créons un fichier base.ldif
cd ~ vi base.ldif
Nous y ajoutons les éléments

Nous ajoutons ces infos à l'annuaire
sudo /usr/local/openldap/bin/ldapadd -x -D "cn=Manager,dc=domain,dc=tld" -W -f base.ldif
Nous listons le contenu de notre annuaire
