# Apache Linux Integration Kit

The Apache Linux Integration Kit allows PingFederate to coordinate user authentication and single sign-on (SSO) *(tooltip: \<div class="paragraph">
\<p>The process of authenticating an identity (signing on) at one website (usually with a user ID and password) and then accessing resources secured by other domains without reauthenticating.\</p>
\</div>)* between an Apache web application and an identity provider (IdP) *(tooltip: \<div class="paragraph">
\<p>A service that manages identity information and provides authentication services to relying clients or SPs within a federated or distributed network.\</p>
\</div>)*.

|   | For new integrations, try the [Agentless Integration Kit](../agentless/pf_agentless_ik.html). It can integrate with a variety of platforms using a modern RESTful approach, and it doesn't require you to integrate agent software into your application. |

## Components

* OpenToken Adapter

  Installed in PingFederate, this adapter uses the secure OpenToken standard to pass user attributes and session information from PingFederate to the Apache agent on the Apache server.

* Apache agent

  Installed on the server running Apache, this program watches for protected resource requests and determines whether to grant access or redirect the user to PingFederate for authentication with an IdP.

## Intended audience

This document is intended for PingFederate administrators.

Learn more about the setup process in the following sections of the PingFederate documentation:
