microsoft.ad.domain_child module – Manage domain children in an existing Active Directory forest.

Note

This module is part of the microsoft.ad collection (version 1.8.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install microsoft.ad.

To use it in a playbook, specify: microsoft.ad.domain_child.

New in microsoft.ad 1.6.0

Synopsis

  • Ensure that a Windows Server host is configured as a domain controller as a new domain in an existing forest.

  • This module may require subsequent use of the ansible.windows.win_reboot action if changes are made.

  • This module will only check if the domain specified by dns_domain_name exists or not. If the domain already exists under the same name, no other options, other than the domain name will be checked during the run.

Note

This module has a corresponding action plugin.

Parameters

Parameter

Comments

create_dns_delegation

boolean

Whether to create a DNS delegation that references the new DNS server that was installed.

Valid for Active Directory-integrated DNS only.

The default is computed automatically based on the environment.

Choices:

  • false

  • true

database_path

path

The path to a directory on a fixed disk of the Windows host where the domain database will be created..

If not set then the default path is %SYSTEMROOT%\NTDS.

dns_domain_name

string

The full DNS name of the domain to create.

When domain_type=child, the parent DNS domain name is derived from this value.

domain_admin_password

string / required

Password for the specified domain_admin_user.

domain_admin_user

string / required

Username of a domain admin for the parent domain.

domain_mode

string

Specifies the domain functional level of child/tree.

The domain functional level cannot be lower than the forest functional level, but it can be higher.

The default is automatically computed and set.

Current known modes are Win2003, Win2008, Win2008R2, Win2012, Win2012R2, WinThreshold, or Win2025.

domain_type

string

Specifies the type of domain to create.

Set to child to create a child of an existing domain as specified by dns_domain_name.

Set to tree to create a new domain tree in an existing forest as specified by parent_domain_name. The dns_domain_name must be the full domain name of the new domain tree to create.

Choices:

  • "child" ← (default)

  • "tree"

install_dns

boolean

Whether to install the DNS service when creating the domain controller.

If not specified then the -InstallDns option is not supplied to the Install-ADDSDomain command, see Install-ADDSDomain for more information.

Choices:

  • false

  • true

log_path

path

Specified the fully qualified, non-UNC path to a directory on a fixed disk of the local computer that will contain the domain log files.

parent_domain_name

string

The fully qualified domain name of an existing parent domain to create a new domain tree in.

This can only be set when domain_type=tree.

reboot

boolean

If true, this will reboot the host if a reboot was required by the module.

If false, this will not reboot the host if a reboot was required and instead sets the reboot_required return value to true.

This cannot be used with async mode.

Choices:

  • false ← (default)

  • true

reboot_timeout

integer

added in microsoft.ad 1.7.0

Maximum seconds to wait for machine to re-appear after a reboot and respond to a test command.

This timeout is evaluated separately for both the reboot verification and test command success so the total timeout can be twice this value.

Default: 600

replication_source_dc

string

added in microsoft.ad 1.8.0

Specifies the name of an existing domain controller in the forest that will be used as the replication source for the new domain.

safe_mode_password

string / required

Safe mode password for the domain controller.

site_name

string

Specifies the name of an existing site where you can place the new domain controller.

sysvol_path

path

The path to a directory on a fixed disk of the Windows host where the Sysvol folder will be created.

If not set then the default path is %SYSTEMROOT%\SYSVOL.

Attributes

Attribute

Support

Description

action

Support: full

Indicates this has a corresponding action plugin so some parts of the options can be executed on the controller

async

Support: partial

Supported for all scenarios except with reboot=True.

Supports being used with the async keyword

bypass_host_loop

Support: none

Forces a ‘global’ task that does not execute per host, this bypasses per host templating and serial, throttle and other loop considerations

Conditionals will work as if run_once is being used, variables used will be from the first available host

This action will not work normally outside of lockstep strategies

check_mode

Support: full

Can run in check_mode and return changed status prediction without modifying target, if not supported the action will be skipped.

diff_mode

Support: none

Will return details on what has changed (or possibly needs changing in check_mode), when in diff mode

platform

Platform: windows

Target OS/families that can be operated against

Notes

Note

  • It is highly recommended to set reboot=true to have Ansible manage the host reboot phase as the actions done by this module puts the host in a state where it may not be possible for Ansible to reconnect in a subsequent task without a reboot.

  • This module must be run on a Windows target host.

  • If using reboot=true, multiple reboots may occur if the host required a reboot before the domain promotion.
