Active Directory Federation Services (ADFS)

This topic explains how to configure a self-hosted ADFS server with LaunchDarkly.

Overview

This topic explains how to configure SSO integration between a self-hosted Active Directory Federation Services (ADFS) server and LaunchDarkly.

ADFS is a service provided by Microsoft as a standard role for Windows Server. It provides a web login using existing Active Directory credentials.

If you need information about ADFS errors during configuration, troubleshoot it by accessing the ADFS logs in the Windows Event Viewer.

Prerequisites

To give your organization access to LaunchDarkly through ADFS, you need the following components:

• An Enterprise LaunchDarkly account.
• A signed SSL certificate.
• An Active Directory instance where all users have an email address attribute.
• A Microsoft Server instance with ADFS installed and configured.

This topic does not tell you how to set up ADFS. To learn how to set up ADFS, read Microsoft’s documentation.

Set up Launch

Darkly fields

Here is a table explaining LaunchDarkly fields:

LaunchDarkly field	Notes
Sign-on URL	Default value: https://YOUR-DOMAIN/adfs/ls/. If the default value fails, confirm that the endpoint is enabled and the URL path is correct. Find the endpoint in Service, then Endpoints. Search for an endpoint with the SAML 2.0/WS-Federation type.
X.509 Certificate	Copy the Token Signing certificate to a Base-64 encoded X.509 file and import it into LaunchDarkly

For more information on configuring LaunchDarkly’s SSO, read Single sign-on.

Configure custom roles

You can map LaunchDarkly custom role attributes to ADFS using a claim issuance policy. To learn more about SSO provisioning for roles, read Roles.

Before you can map custom role attributes, you must get your ADFS groups. To learn how, read Microsoft’s Create a Rule to Send Claims Using a Custom Rule.

Your rule will look something like this:

To send claims using a custom rule:

Here is an image of the custom rule:

9. Click OK.

You can now assign ADFS members to custom role groups using the “Member of” tab within user properties.

SAML ignores empty fields if used in Roles or customRoles. To clear all existing roles, enter an empty string "" into the field.

Test drive and enable

After you successfully complete the procedures in this topic, you can log in through ADFS when test-drive mode is enabled. To learn more, read Test-drive mode.

If you are able to successfully log in with test-drive mode enabled, you can enable SSO for the rest of your organization. To learn more, read Single sign-on.
