Windows の Active Directory ドメインに参加します。
LAN 内に Windows Active Directory Domain Service が稼働していることが前提です。
ここでは例として、以下のような Active Directory ドメイン環境で設定します。

apt -y install realmd sssd sssd-tools adcli krb5-user packagekit samba-common samba-common-bin samba-libs # DHCP 使用中の場合は [Yes], そうでない場合は [No] +----------------------+ Samba server and utilities +-----------------------+ | | | If your computer gets IP address information from a DHCP server on the | | network, the DHCP server may also provide information about WINS servers | | ("NetBIOS name servers") present on the network. This requires a change | | to your smb.conf file so that DHCP-provided WINS settings will | | automatically be read from /var/lib/samba/dhcp.conf. | | | | The dhcp-client package must be installed to take advantage of this | | feature. | | | | Modify smb.conf to use WINS settings from DHCP? | | | | <Yes> <No> | | | +---------------------------------------------------------------------------+ # 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. Often, the default realm is the uppercase version of the local | | DNS domain. | | | | Default Kerberos version 5 realm: | | | | SRV.WORLD________________________________________________________________ | | | | <Ok> | | | +---------------------------------------------------------------------------+ # AD DS のホスト名を指定 +------------------+ Configuring Kerberos Authentication +------------------+ | Enter the hostnames of Kerberos servers in the SRV.WORLD Kerberos realm | | separated by spaces. | | | | Kerberos servers for your realm: | | | | fd3s.srv.world___________________________________________________________ | | | | <Ok> | | | +---------------------------------------------------------------------------+ # AD DS のホスト名を指定 +------------------+ Configuring Kerberos Authentication +------------------+ | Enter the hostname of the administrative (password changing) server for | | the SRV.WORLD Kerberos realm. | | | | Administrative server for your Kerberos realm: | | | | fd3s.srv.world___________________________________________________________ | | | | >Ok< | | | +---------------------------------------------------------------------------+ |
