Please update your inventory.yml file with the correct target_hostname.
|
|
Example:
|
|
all:
|
|
hosts:
|
|
your-server:
|
|
ansible_host: your_server_ip
|
|
target_hostname: your-desired-hostname
|
|
samba_realm: your.domain.local
|
|
|
|
The target_hostname must be set in inventory for Samba4 domain controller installation.
