Samba PDC#1 - サーバーの設定
2015/01/19
 
Samba + OpenLDAP で Samba PDC (プライマリドメインコントローラ)を構築します。 LAN内にLDAPサーバー構築済み、且つ、 この Samba PDC にするサーバーはLDAPクライアントである必要があります。
[1] まずはOpenLDAPの設定を変更しておきます。
[root@dir ~]#
yum -y install samba
[root@dir ~]#
cp /usr/share/doc/samba-*/LDAP/samba.schema /etc/openldap/schema/

[root@dir ~]#
vi /etc/openldap/slapd.conf
include         /etc/openldap/schema/core.schema
include         /etc/openldap/schema/cosine.schema
include         /etc/openldap/schema/inetorgperson.schema
include         /etc/openldap/schema/nis.schema
# 追記

include         /etc/openldap/schema/samba.schema

# 追記

access to attrs=userPassword,
sambaLMPassword,sambaNTPassword

    by self write
    by dn="cn=Manager,dc=server,dc=world" write
    by anonymous auth
    by * none

[root@dir ~]#
/etc/rc.d/init.d/ldap restart

[2] smbldap-tools をインストールし、Sambaを設定変更してLDAP認証にします。
[root@lan ~]#
yum --enablerepo=epel -y install smbldap-tools
 
# EPELからインストール

Before starting, check
 . if your samba controller is up and running.
 . if the domain SID is defined (you can get it with the 'net getlocalsid')

 . you can leave the configuration using the Ctrl-c key combination
