# Sécurité Active Directory

## 👥 Qu'est-ce que la sécurité Active Directory ?

En utilisant le [Active Directory](/fr/installation-setup/installation/active-directory.md) sécurité vous pouvez restreindre l'accès à votre Sondage aux utilisateurs disposant d'un compte Active Directory valide. Cet élément de sécurité peut être configuré pour autoriser soit le single sign on, soit pour laisser les utilisateurs se connecter manuellement en utilisant leurs identifiants Active Directory. 

## 🔅 Propriétés de la sécurité Active Directory

* **`Autoriser les soumissions multiples`** les Répondants peuvent participer plusieurs fois au même Sondage.
* **`Single sign on`** l'utilisateur doit déjà être connecté avec ses identifiants Active Directory dans son navigateur. Si vous ne souhaitez pas laisser le répondant saisir ses identifiants manuellement, vous pouvez désactiver le single sign on.

{% hint style="warning" %}
Le single sign on nécessite que le module Active Directory de ngSurvey soit configuré pour [prise en charge du single sign on](/fr/installation-setup/installation/active-directory/active-directory-setup.md).
{% endhint %}

{% hint style="success" %}
Cet élément de sécurité peut être utilisé comme [fournisseur de clé](/fr/form-management/security/key-provider-concepts.md). 
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.ngsurvey.com/fr/form-management/security/security-items/active-directory-security.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
