CentOS7 Servers aan LDAP koppelen

Deze instructies resulteren in dat de betreffende server voor de authenticatie de LDAP server met IP nummer 192.168.1.230 raadpleegt.

Via pam-ldap

Installeer ssoftware

yum install -y openldap-clients nss-pam-ldapd

Configureer de authenticatie module

authconfig --enableldap --enableldapauth --ldapserver=192.168.1.230 --ldapbasedn="dc=voorbeeld,dc=lan" --enablemkhomedir --update

systemctl restart nslcd

En test: getent passwd testuser

testuser:x:1000:1000:testuser:/home/testuser:/bin/bash

Hierna kan je als testuser proberen in te loggen.

via sssd

log in als root op de te koppelen client en gebruik authconfig om sssd te configureren:

authconfig --enablesssd --enablesssdauth --enableldap --enableldapauth --enablemkhomedir --ldapserver=ldap://192.168.122.230 --ldapbasedn="dc=test-net,dc=isae" --enablelocauthorize --update

chmod 600 /etc/sssd/sssd.conf systemctl restart sssd

De resulterende sssd.conf file ziet er daarna als volgt uit:

[domain/default]
autofs_provider = ldap
cache_credentials = True
ldap_search_base = dc=test-net,dc=isae
id_provider = ldap
auth_provider = ldap
chpass_provider = ldap
ldap_uri = ldap://192.168.122.230
ldap_id_use_start_tls = True
ldap_tls_cacertdir = /etc/openldap/cacerts

[sssd]
config_file_version = 2
services = nss, pam, autofs
domains =  isae_ldap

[nss]

[pam]

[domain/isae_ldap]
id_provider = ldap
auth_provider = ldap
chpass_provider = ldap
ldap_uri = ldap://192.168.122.230
ldap_search_base = dc=test-net,dc=isae
ldap_id_use_start_tls = True
ldap_tls_reqcert = never
ldap_tls_cacertdir = /etc/openldap/certs/
ldap_tls_cacert = /etc/openldap/cacerts/isae.pem
[autofs]
