Join the Active Directory Domain

Administrator - user with the admin permissions in the AD DC

sudo net ads join -U Administrator

// (OR ???)

// /usr/sbin/realm join --user=Administrator --user-principal="host/{{ ansible_nodename }}.{{ domain | lower }}@{{ domain }}" --computer-ou="{{ computer_ou }}" {{ admin_server }}'

Start services

sudo systemctl enable --now smbd nmbd

sudo systemctl enable --now winbind

After Samba is running, we can query AD for user information:

sudo getent passwd "DOMAIN01\Administrator"

(OR)

sudo getent passwd "avchishko_sv@domain01.local"

    ...
    smith_g@domain01.local:*:1433301252:1433301252:Gabriel Smith (smith_g):/home/smith_g:/bin/bash
