# Shibboleth SP3 SSO

## Overview

Clients that are already using [Shibboleth Service Provider 3](https://wiki.shibboleth.net/confluence/display/SP3/Home) to manage resource access (such as services or applications) can quickly integrate with WorkflowGen by offering users Single Sign-On (SSO) authentication for a secure and seamless user experience.

For this, Shibboleth SP3 provides a native module for IIS 7 and later that passes user information to WorkflowGen via the `REMOTE_USER` environment variable.

The WorkflowGen website and web apps should have only the `Anonymous Authentication` method enabled under the IIS Manager Authentication feature page.

## Installation

For installation and configuration details, see the [Shibboleth SP3 IIS](https://wiki.shibboleth.net/confluence/display/SP3/IIS) documentation.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.workflowgen.com/integration/7.22/custom-authentication/shibboleth-sp3-sso.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
