Samba BDC
2010/08/17
  Samba BDC (バックアップドメインコントローラ) を構築します。 当然のことながら同一サブネット内にSamba PDC 構築済みが前提です。 また、この Samba BDC はLDAPクライアントである必要があります。 Samba PDC は同一サブネット内に一つのみ存在できますが、この Samba BDC はいくらでも構築することができます。

[1] smb.conf の設定はほぼプライマリ側と同じです。異なるのはプライマリ側が「domain master = Yes」に対して、 バックアップ側は「domain master = No」になる箇所と、LDAPサーバーのIPのみです。

smbldap-tools script configuration

-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

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 Crtl-c key combination
. empty value can be set with the "." character
