# google\_active\_directory\_domain\_trust

Adds a trust between Active Directory domains


To get more information about DomainTrust, see:

* [API documentation](https://cloud.google.com/managed-microsoft-ad/reference/rest/v1/projects.locations.global.domains/attachTrust)
* How-to Guides
    * [Active Directory Trust](https://cloud.google.com/managed-microsoft-ad/docs/create-one-way-trust)

~> **Warning:** All arguments including the following potentially sensitive
values will be stored in the raw state as plain text: `trust_handshake_secret`.
[Read more about sensitive data in state](https://www.terraform.io/language/state/sensitive-data).

## Example Usage - Active Directory Domain Trust Basic


```hcl
resource "google_active_directory_domain_trust" "ad-domain-trust" {
    domain     = "test-managed-ad.com"
    target_domain_name = "example-gcp.com"
    target_dns_ip_addresses = ["10.1.0.100"]
    trust_direction         = "OUTBOUND"
    trust_type              = "FOREST"
    trust_handshake_secret  = "Testing1!"
}
```

## Argument Reference

The following arguments are supported:


* `target_domain_name` -
  (Required)
  The fully qualified target domain name which will be in trust with the current domain.

* `trust_type` -
  (Required)
  The type of trust represented by the trust resource.
  Possible values are: `FOREST`, `EXTERNAL`.

* `trust_direction` -
  (Required)
  The trust direction, which decides if the current domain is trusted, trusting, or both.
  Possible values are: `INBOUND`, `OUTBOUND`, `BIDIRECTIONAL`.

* `target_dns_ip_addresses` -
  (Required)
  The target DNS server IP addresses which can resolve the remote domain involved in the trust.

* `trust_handshake_secret` -
  (Required)
  The trust secret used for the handshake with the target domain. This will not be stored.
  **Note**: This property is sensitive and will not be displayed in the plan.

* `domain` -
  (Required)
  The fully qualified domain name. e.g. mydomain.myorganization.com, with the restrictions,
  https://cloud.google.com/managed-microsoft-ad/reference/rest/v1/projects.locations.global.domains.


- - -


* `selective_authentication` -
  (Optional)
  Whether the trusted side has forest/domain wide access or selective access to an approved set of resources.

* `project` - (Optional) The ID of the project in which the resource belongs.
    If it is not provided, the provider project is used.


## Attributes Reference

In addition to the arguments listed above, the following computed attributes are exported:

* `id` - an identifier for the resource with format `projects/{{project}}/locations/global/domains/{{domain}}/{{target_domain_name}}`


## Timeouts

This resource provides the following
[Timeouts](https://developer.hashicorp.com/terraform/plugin/sdkv2/resources/retries-and-customizable-timeouts) configuration options:

- `create` - Default is 20 minutes.
- `update` - Default is 20 minutes.
- `delete` - Default is 20 minutes.

## Import


DomainTrust can be imported using any of these accepted formats:

* `projects/{{project}}/locations/global/domains/{{domain}}/{{target_domain_name}}`
* `{{project}}/{{domain}}/{{target_domain_name}}`
* `{{domain}}/{{target_domain_name}}`


In Terraform v1.5.0 and later, use an [`import` block](https://developer.hashicorp.com/terraform/language/import) to import DomainTrust using one of the formats above. For example:

```tf
import {
  id = "projects/{{project}}/locations/global/domains/{{domain}}/{{target_domain_name}}"
  to = google_active_directory_domain_trust.default
}
```

When using the [`terraform import` command](https://developer.hashicorp.com/terraform/cli/commands/import), DomainTrust can be imported using one of the formats above. For example:

```
$ terraform import google_active_directory_domain_trust.default projects/{{project}}/locations/global/domains/{{domain}}/{{target_domain_name}}
$ terraform import google_active_directory_domain_trust.default {{project}}/{{domain}}/{{target_domain_name}}
$ terraform import google_active_directory_domain_trust.default {{domain}}/{{target_domain_name}}
```

## User Project Overrides

This resource supports [User Project Overrides](https://registry.terraform.io/providers/hashicorp/google/latest/docs/guides/provider_reference#user_project_override).
