LDAP Server Installation

"Тихая" установка

DEBIAN_FRONTEND=noninteractive apt-get install slapd ldap-utils

Современные дистрибутивы OpenLDAP используют сам LDAP как хранилище конфигурации.

Посмотреть содержимое можно так:

ldapsearch -Y EXTERNAL -H ldapi:///  -b "cn=config"

ldapadd  -Y EXTERNAL -H ldapi:/// <  database
SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth
SASL SSF: 0
adding new entry "olcDatabase={2}hdb,cn=config"

Для работы создаем свой домен куда будем помещать все объекты.

LDAP Configuration

alias ldapsearch='ldapsearch -D "cn=admin,dc=fuel" -w r00tme'
alias ldapmodify='ldapmodify -D "cn=admin,dc=fuel" -w r00tme'

dc: example_organization
o: Example Organization
objectClass: dcObject
objectClass: organization
