installation dans /usr/local/openldap

[root@ldapex ~]# cd /usr/local/openldap/etc/openldap/

utilisation d'un script maison pour reconstruction de la config OLC (slpad.d) depuis un fichier de configuration traditionnel slapd.conf, avec arborescence de type ltb-project (/usr/local/openldap)

[root@ldapex openldap]# cat olcgene.sh 
systemctl stop slapd
cd /usr/local/openldap/etc/openldap/slapd.d
rm -rf *
cd ..
/usr/local/openldap/sbin/slaptest -f /usr/local/openldap/etc/openldap/slapd.conf -F /usr/local/openldap/etc/openldap/slapd.d
chown -R ldap:ldap /usr/local/openldap/etc/openldap/slapd.d
chown -R ldap:ldap /usr/local/openldap/var/openldap-data
systemctl start slapd

éléments ajoutés pour une configuration incluant plusieurs schema (supann, eduperson etc …)

Script qui permet de recontruire complement le replica partiel , avec injection de l'arborescence de base (dc=int,dc=fr et le compte de requttage dans ou=dsa) puis relance avec syncrepl pour recuperer toutes les entrée ou=people depuis le master .
