+# AD FS
+
+The folowing example does the following: 
+
+Terraform:
+
+- (Optional) Creates a project.
+- (Optional) Creates a VPC.
+- Sets up managed AD
+- Creates a server where AD FS will be installed. This machine will also act as admin workstation for AD. 
+- Exposes AD FS using GLB.
+
+Ansible:
+
+- Installs the required Windows features and joins the computer to the AD domain.
+- Provisions some tests users, groups and group memberships in AD. The data to provision is in the ifles directory of the ad-provisioning ansible role. There is script available in the scripts/ad-provisioning folder that you can use to generate an alternative users or memberships file. 
+- Installs AD FS
+
+In addition to this, we also include a Powershell script that facilitates the configuration required for Anthos when authenticating users with AD FS as IdP.
+
+The diagram below depicts the architecture of the example:
+
+![Architecture](architecture.png)
+
+## Running the example
+
+Clone this repository or [open it in cloud shell](https://ssh.cloud.google.com/cloudshell/editor?cloudshell_git_repo=https%3A%2F%2Fgithub.com%2Fterraform-google-modules%2Fcloud-foundation-fabric&cloudshell_print=cloud-shell-readme.txt&cloudshell_working_dir=examples%2Fcloud-operations%2Fadfs), then go through the following steps to create resources:
+
+* `terraform init`
+* `terraform apply -var project_id=my-project-id -var ad_dns_domain_name=my-domain.org -var adfs_dns_domain_name=adfs.my-domain.org`
+
+Once the resources have been created, do the following:
+
+1. Create an A record to point the AD FS DNS domain name to the public IP address returned after the terraform configuration was applied.
+
+2. Run the ansible playbook
+
+        ansible-playbook playbook.yaml
+
+# Testing the example
+
+1. In your browser open the following URL:
+
+        https://adfs.my-domain.org/adfs/ls/IdpInitiatedSignOn.aspx
+
+2. Enter the username and password of one of the users provisioned. The username has to be in the format: [email protected]
+
+3. Verify that you have successfuly signed in.
+
+Once done testing, you can clean up resources by running `terraform destroy`.
