Integrating VMware Identity Manager as a SAML 2.0 Identity Provider for Splunk Enterprise Authentication

In this blog post, I will outline the process for integrating VMware Identity Manager (vIDM) as a SAML 2.0 identity provider (IdP) for Splunk Enterprise authentication. This integration allows for single sign-on (SSO) between vIDM and Splunk Enterprise, making it easier for users to access both systems without having to log in multiple times.

Introduction

————

Splunk Enterprise is a powerful monitoring and analytics platform that helps organizations gain insights from their data. VMware Identity Manager (vIDM) is an enterprise-class identity Governance solution that provides a simple, secure way to manage access to applications and data. By integrating vIDM as an IdP for Splunk Enterprise authentication, we can leverage the power of both systems to provide a seamless user experience.

Prerequisites

————-

Before starting this integration, there are a few things you need to have in place:

* A working knowledge of VMware Identity Manager and Splunk Enterprise

* A valid license for VMware Identity Manager and Splunk Enterprise

* A properly configured vIDM environment with at least one user account created

* A properly configured Splunk Enterprise environment with at least one user account created

Step 1: Downloading the SP Metadata File from Splunk Enterprise

———————————————————

The first step is to download the Service Provider (SP) metadata file from Splunk Enterprise. To do this, follow these steps:

* Open a web browser and navigate to your Splunk Enterprise server’s URL (e.g., .com>).

* Log in to your Splunk Enterprise server using your admin credentials.

* Once logged in, click on the “Settings” icon (represented by a gear) in the top right corner of the page, then select “Authentication” from the left menu.

* Scroll down to the “Service Provider Metadata” section and click the “Download SP Metadata” button.

* Save the downloaded file to a location on your system that you can easily find later (e.g., Desktop).

Step 2: Creating a New Web Application in VMware Identity Manager

———————————————–

Next, we will create a new web application in vIDM for Splunk Enterprise. Follow these steps:

* Log in to the vIDM administrator console at .com>).

* Click on the “Catalog” tab in the top menu bar.

* Click the “New” button at the top right corner of the page.

* In the “Create a New Item” wizard, select “Web Application” as the item type and click “Next”.

* In the “Name” field, enter a name for your Splunk Enterprise web application (e.g., “Splunk – Administrator”).

* Leave all of the remaining optional fields blank and click “Next”.

Step 3: Configuring Custom Attribute Mapping

—————————————

Next, we will configure custom attribute mapping for the Splunk Enterprise web application. Follow these steps:

* In the “Application Parameters” section of the wizard, click the “Advanced Properties” link to expose additional advanced property fields.

* Scroll down to the “Custom Attribute Mapping” section and click the “Add Row” button three times.

* In the first two rows, enter the following attributes:
