Creating an Active Directory server on Google Cloud for Pinniped integration tests

This documents the steps that were taken to create our test AD server used by the integration tests. The integration tests use LDAPS and StartTLS to connect to the AD server.

Create a Windows Server VM and configure it as an AD Domain Controller

The steps in this section were mostly inspired by https://cloud.google.com/architecture/deploy-an-active-directory-forest-on-compute-engine.

From your Mac, create a VPC, subnet, firewall rules, admin password, reserved static IP, and the VM itself.

On your Mac:

# Login as yourself.
gcloud auth login

# Set some variables.
project="REDACTED" # Change this to be the actual project name before running these commands.
region="us-central1"
zone="us-central1-b"
vpc_name="ad"

# Create VPC.
gcloud compute networks create ${vpc_name} \
  --project ${project} \

# Create subnet.
# The google tutorial says to "enable Private Google Access so that Windows can activate without internet access."

  --project ${project} --region ${region} \
  --network ${vpc_name} \
  --range "10.0.0.0/28" \

# Create a firewall rule to allow RDP. Find out what your public IP address is by going to https://whatismyipaddress.com.
# Replace the X.X.X.X placeholder address shown here with your real IPv4 address.
my_ip=X.X.X.X

# Allow LDAP (port 389) from the whole internet, to allow the integration tests to use StartTLS.

# This creates a service account called ad-domaincontroller@PROJECT_NAME.iam.gserviceaccount.com
# (where PROJECT_NAME is the actual GCP project name) and sets the account name to the
# variable $dcServiceAccount.
dcServiceAccount=$(gcloud iam service-accounts create ad-domaincontroller \
  --project ${project} \
  --display-name "AD Domain Controller VM Service Account" \
  --format "value(email)")

# Allow the new service account to temporarily read the Windows admin password from secret manager.
# The following `date` command might only work on MacOS. It prints the time like this: 2024-10-23T19:20:36Z

Update DNS

Update the Cloud DNS entry for activedirectory.test.pinniped.dev. to be an "A" record pointing to the public static IP of the VM. This is easier to do in the Cloud DNS UI in your browser. It would take many gcloud CLI commands to accomplish the same task.

Configure test users and groups

Make sure you have an RDP client installed. On a Mac, you can install RDP from the App Store. It was recently renamed "Windows App".

Note: To copy/paste in the RDP client, you may need to use CTRL-C/CTRL-V if CMD-C/CMD-V don't work.

RDP into the Windows VM. To connect, use activedirectory.test.pinniped.dev as the name of the server, the username Administrator, and the password from the active-directory-dc1-password entry in Secrets Manager. You can ignore the RDP certificate error.

In your RDP session, open Powershell. Then run the following commands to add some users and groups, change the password policy, and grant some permissions.

Before running the commands, replace the redacted passwords as follows:

The value for REDACTED_BIND_USER_PASSWORD can be found at aws-ad-bind-account-password in the concourse-secrets secret
The value for REDACTED_PINNY_USER_PASSWORD can be found at aws-ad-user-password in the concourse-secrets secret
The value for REDACTED_DEACTIVATED_USER_PASSWORD can be found at aws-ad-deactivated-user-password in the concourse-secrets secret

If you would like to see these OUs, users, and groups in the UI, you can open the "Active Directory Users and Computers" app in your RDP session.

Configure a CA and a serving certificate for LDAPS

Now we need to create and configure a TLS serving certificate for LDAPS.

The certificate needs to include two hostnames. One of the hostnames is the name that the AD server thinks is its own hostname (active-directory-dc1.activedirectory.test.pinniped.dev). This is how the AD server will decide to use this cert for the LDAPS port. The other hostname is the one that clients will use when making connections from the outside (activedirectory.test.pinniped.dev) so they can validate the server certificate.

The steps here were inspired by https://gist.github.com/magnetikonline/0ccdabfec58eb1929c997d22e7341e45.

On your mac:

# On your Mac: Create a self-signed CA public/private keypair.
openssl req -x509 -newkey rsa:4096 \
  -keyout ad-ca.key -out ad-ca.crt \
  -sha256 -days 36500 -nodes \
  -subj "/C=US/ST=California/L=San Francisco/O=Pinniped/OU=Pinniped CI/CN=Pinniped AD CA"

# Copy the public key to your clipboard.
cat ad-ca.crt| pbcopy

In Powershell terminal:

# In your Windows RDP session's Powershell terminal, put the content of the clipboard into a file.
# Note that if you copy/paste this command to your RDP session, then you need to pbcopy the public
# key again before you hit return for this command.
Get-Clipboard | Out-File -FilePath "C:\users\administrator\desktop\ca.crt"

# In Powershell terminal, check that the file exists and looks correct.
type "C:\users\administrator\desktop\ca.crt"

# Import root certificate into trusted store of domain controller in your Powershell terminal:
Import-Certificate -FilePath "C:\users\administrator\desktop\ca.crt" -CertStoreLocation Cert:\LocalMachine\Root

If you want to validate that this was imported, open the UI tool called "Manage computer certificates" and look in the folder called "Trusted Root Certification Authorities\Certificates". If the UI was already open, click the refresh button.

Copy the following file contents to your clipboard:

_continue_ = "DNS=activedirectory.test.pinniped.dev"
_continue_ = "DNS=active-directory-dc1.activedirectory.test.pinniped.dev"

In Powershell terminal:

# In your Windows RDP session's Powershell terminal, put the content of the clipboard into a file.
# Note that if you copy/paste this command to your RDP session, then you need to copy the file contents
# from above again before you hit return for this command.
Get-Clipboard | Out-File -FilePath "C:\users\administrator\desktop\request.inf"

# In Powershell terminal, check that the file exists and looks correct.
type "C:\users\administrator\desktop\request.inf"

# Create a CSR. This command will also generate a private key for the AD server and save it.
certreq -new "C:\users\administrator\desktop\request.inf" "C:\users\administrator\desktop\client.csr"

# Show the CSR.
type "C:\users\administrator\desktop\client.csr"

# Copy the content of this file to your clipboard.
Get-Content "C:\users\administrator\desktop\client.csr" | Set-Clipboard

On your mac:

# On your Mac, use the CA to issue a serving cert based on the CSR.

# Note that if you copy/paste this command to your RDP session, then you need to pbcopy the file contents
# from above again before you hit return for this command.
Get-Clipboard | Out-File -FilePath "C:\users\administrator\desktop\client.crt"

# In Powershell terminal, check that the file exists and looks correct.
type "C:\users\administrator\desktop\client.crt"

# Add the serving certificate to Windows. This will also automatically associate it to the private key that you
# generated with the previous usage of certreq.
certreq -accept "C:\users\administrator\desktop\client.crt"

# If you want to validate that this was imported, open the UI tool called "Manage computer certificates"
# and look in the folder called "Personal\Certificates". If the UI was already open, click the refresh button.
# Double click on the cert. Ensure that it says, "you have a private key that corresponds to this certificate".
# Next, we need to reboot the VM for the cert to get picked up and used for serving incoming LDAPS connections.
# After showing you a warning dialog box, this should terminate your RDP session and stop the VM.
shutdown /s

Wait for the VM to stop, then start the VM again from your Mac:

gcloud compute instances start active-directory-dc1 --project ${project} --zone ${zone}

Wait for the VM to finish booting. Then we can confirm that LDAPS is working. On your Mac:

# Check that serving cert is being returned on the LDAPS port. This command should show the cert chain.
# It should also verify the server cert using our CA. The output should include "Verify return code: 0 (ok)".
openssl s_client -connect activedirectory.test.pinniped.dev:636 -showcerts -CAfile ad-ca.crt < /dev/null

# Unfortunately, the ldapsearch command that comes pre-installed on MacOS does not seem to respect
# the LDAPTLS_CACERT env variable. So it will not be able to validate the server certificates.
# As a workaround, we can use docker to run ldapsearch commands in a linux container.

# Test the regular LDAP port by issuing a query on your Mac. The -ZZ option asks it to use StartTLS.
# This should list all users. Replace REDACTED_BIND_USER_PASSWORD with the real password.
docker run -v "$(pwd):/certs" -e LDAPTLS_CACERT="/certs/ad-ca.crt" --rm -it bitnami/openldap \
  ldapsearch -d8 -v -x -ZZ -H 'ldap://activedirectory.test.pinniped.dev' \

Update the `concourse-secrets` secret in GCP Secrets Manager

On your Mac:

# Copy the CA's public cert.
cat ad-ca.crt | base64 | pbcopy

# cd to your local clone of the `ci` branch of the pinniped repo
cd pinniped-ci-branch

# Edit the secret.
./hack/edit-gcloud-secret.sh concourse-secret
# This opens vim to edit the secret.
# Paste the cert as the value for `aws-ad-ca-data`.
# Also edit the the value of `aws-ad-user-unique-id-attribute-value`. The value should be the ObjectGUID of the pinny
# user that you created in the steps above.
# Save your changes, exit vim, and when prompted say that you want to save this as the new version of concourse-secrets.

Confirm that Active Directory integration tests can pass

Use these commands run all the Active Directory integration tests on your Mac. The -run filter is based on the tests as they existed at the time of writing this doc. You can find AD tests by searching for SkipTestWhenActiveDirectoryIsUnavailable.

On your Mac:

# Login so we can read the secrets from GCP Secret Manager.
gcloud auth login

# cd to your local git clone
cd pinniped

# Compile and install onto a local kind cluster.
./hack/prepare-for-integration-tests.sh -c --get-active-directory-vars "../pinniped-ci-branch/hack/get-aws-ad-env-vars.sh"

# Run all the tests that depend on AD.
source /tmp/integration-test-env && go test -v -race -count 1 -timeout 0 ./test/integration \
  -run "/TestSupervisorLogin_Browser/active_directory|/TestE2EFullIntegration_Browser/with_Supervisor_ActiveDirectory|/TestActiveDirectoryIDPPhaseAndConditions_Parallel|/TestSupervisorWarnings_Browser/Active_Directory"

Cleanup

On your Mac:

# Remove all bindings for the service account from the secret.
# The binding was only needed during the first boot of the VM.

# a new firewall rule to allow it.
