Samba Winbind で Windows の Active Directory ドメインに参加します。
ローカルネットワーク内に Windows Active Directory Domain Service が稼働していることが前提です。
当例では、以下のような Active Directory ドメイン環境で設定します。

root@smb:~#
apt -y install winbind libpam-winbind libnss-winbind krb5-config samba-dsdb-modules samba-vfs-modules # レルム名を指定 +------------------+ Configuring Kerberos Authentication +------------------+ | When users attempt to use Kerberos and specify a principal or user name | | without specifying what administrative Kerberos realm that principal | | belongs to, the system appends the default realm. The default realm may | | also be used as the realm of a Kerberos service running on the local | | machine.
