Poniżej znajdują się przykładowe pliki konfiguracyjne niektórych usług podłączonych do LDAP omawianych na kursie.

• Plik konfiguracyjny: slapd.conf
• Konfiguracja saslauthd (pamiętaj o dopisaniu pwcheck_method: saslauthd do /etc/sasl/slapd.conf i opcji -a ldap do saslauthd):

  saslauthd.conf

  ldap_servers: ldapi://
  ldap_bind_dn: uid=saslauthd,ou=System,dc=example,dc=com
  ldap_password: haslo
  ldap_search_base: dc=example,dc=com
  ldap_mech: SIMPLE
  ldap_auth_method: bind

• Konfiguracja narzędzi klienckich LDAP (ldapsearch, ldapvi itp) - /etc/ldap/ldap.conf:

  ldap.conf

  BASE	dc=example,dc=com
  URI	ldapi://
  TLS_CACERTDIR	/etc/ssl/certs/
  TLS_REQCERT never

• Konfiguracja modułu pam_ldap i nss_ldap (może się nazywać również pam_ldap.conf, nss_ldap.conf - zależnie od dystrybucji):

  ldap.conf

  uri ldapi://
  binddn uid=nssproxy,ou=System,dc=example,dc=com
  bindpw secret
  rootbinddn uid=remoteroot,dc=System,dc=example,dc=com
  
  base dc=example,dc=com
  scope sub
  
  pam_password exop

• Konfiguracja nslcd (może też się nazywać nss-ldapd.conf):

  nslcd.conf

  uid nslcd
  gid nslcd
  
  uri ldapi://
  base dc=example,dc=com
  ldap_version 3
  
  binddn uid=nssproxy,ou=System,dc=example,dc=com
  bindpw secret
  
  scope sub

dovecot.conf

# (...)
auth default {
  mechanisms = plain login
  passdb ldap {
    args = /etc/dovecot/dovecot-ldap.conf
  }
  
  # to pobieramy od razu przy sprawdzaniu hasła
  userdb prefetch {
  }
  
  # dla serwerów SMTP (Postfix/Exim)
  socket listen {
    client {
      path = /var/run/dovecot/auth-client
      group = sasl
      mode = 0660
    }
  }
}
# (...)

W Dovecot 2.x konfiguracja jest podobna, tylko rozmieszczona w osobnych plikach, należy przejrzeć 10-auth.conf (includy na końcu), auth-ldap.conf.ext, 10-master.conf (zamiast "socket listen" będzie "unix_listener").
