Docker container for using a Samba Active Directory server in your network.

As a Samba domain controller needs it's own fixed IP in the network, this container needs to run privileged as root using a macvlan network.

The container needs 3 environment variables to run.

Environment variable	Description	Example
DOMAIN_FQDN	The internal domain name used on the network. This can be a .internal domain.	companyname.internal
DOMAIN_NETBIOS	The Netbios domain name for the AD domain. Username login will become <DOMAIN_NETBIOS>\Administrator for example	PALANTHIR
DNSFORWARDER	The DNS server the Samba DNS server uses as DNS forwarder	1.1.1.1

Installation

Create the volumes needed, for example:

sudo podman volume create ad_dc1_conf
sudo podman volume create ad_dc1_sambalib

build the image

sudo podman build -t samba-ad-docker --network host https://git.palanthir.nl/palanthir/samba-ad-docker.git

sudo podman build -t samba-ad-docker .

start the container

sudo podman run --name ad_dc1
-e DOMAIN_FQDN=
-e DOMAIN_NETBIOS=
-e DNSFORWARDER=
-e TLS_KEY_FILE=
-e TLS_CERT_FILE=
-e TLS_CA_FILE=
--network=LANnetwork --ip= --ip6=
--replace --privileged -d --hostname=
-v ad_dc1_conf:/etc/samba/config
-v ad_dc1_sambalib:/var/lib/samba
localhost/samba-ad-docker

Set the Administrator password

podman exec -it <container name> samba-tool user setpassword Administrator

Handy command to view all DNS hosts in the AD domain:

samba-tool dns query localhost <domain name> @ ALL -U Administrator
