# terraform-aws-identity-center-users

[![Release][release-badge]][latest-release]

💡 Learn more about Masterpoint [below](#who-we-are-𐦂𖨆𐀪𖠋).

## Purpose and Functionality

This Terraform module provisions, configures, and manages AWS IAM Identity Center (SSO) with built-in user provisioning, including assigning users, groups, and permission sets.

- This is designed to be seamless for organizations that want to **manage users within the AWS Identity Center directory as their identity source** instead of an external identity provider (such as Okta, Azure Active Directory, etc.). This means that all users are managed by IaC.

### Notes

- Authentication is handled by AWS Identity Center. Upon user creation by TF, the user will be in AWS Identity Center directory.

  - However, the AWS Terraform provider does not support the setting the option to send credentials/verification email after creation, so the administrator must go into the AWS Identity Center directory console and and enable ["Send email OTP for users created from API"](https://docs.aws.amazon.com/singlesignon/latest/userguide/userswithoutpwd.html), or manually request to send a verification email per each user so users can reset their own password.

## Usage

### Prerequisites

- You will need to manually (ClickOps) enable AWS Identity Center & create an SSO instance in the AWS account that you want to be set as the "management account" for your organization. See https://docs.aws.amazon.com/singlesignon/latest/userguide/enable-identity-center.html.

  - The SSO instance itself is not managed by Terraform, there is no Terraform resource for it. Settings like MFA configurations must be updated on the AWS console ClickOps.

- After enabling, Terraform can reference it using the `data "aws_ssoadmin_instances" "sso" {}` data source.

### See below for a simplistic example of how to use this module

```hcl

data "aws_ssoadmin_instances" "sso" {}

locals {

  instance_arn      = tolist(data.aws_ssoadmin_instances.sso.arns)[0]

  identity_store_id = tolist(data.aws_ssoadmin_instances.sso.identity_store_ids)[0]

}

module "aws_sso" {

  source = "github.com/masterpointio/terraform-aws-identity-center-users?ref=v1.x.x"

  instance_arn      = local.instance_arn

  identity_store_id = local.identity_store_id

  users = [

    {

      user_name   = "john.doe"

      given_name  = "John"

      family_name = "Doe"

      email       = "john.doe@example.com"

    },

  ]

  groups = [

    {

      name        = "Administrators"

      description = "Full administrative access"

      members     = ["john.doe"]

      assignments = [

        {

          permission_set = "AdministratorAccess"

          account_ids    = ["123456789012", "234567890123"]

        }

      ]

    },

  ]

  permission_sets = [

    {

      name             = "AdministratorAccess"

      description      = "Full administrator access to an account."

      session_duration = "PT12H"

      managed_policies = [

        "arn:aws:iam::aws:policy/AdministratorAccess"

      ]

    }

  ]

}

```

Here are some examples of using this module:

- [`examples/complete`](./examples/complete) - example using a `tfvars` file to manage users, groups, and permission sets

- [`examples/json-user-management`](./examples/json-user-management) - example using a `json` file to manage users, groups, and permission sets

- [`examples/yaml-user-management`](./examples/yaml-user-management) - example using a `yaml` file to manage users, groups, and permission sets
