As extensões de certificado permitem-lhe registar um campo transportado pelos seus certificados para que uma regra o possa ler diretamente, seja um OID personalizado privado emitido pela sua própria PKI, seja um campo padrão como o subject, o SAN ou um atributo do emissor. Depois de registada, a extensão aparece como uma origem nos filtros de Atributo do Certificado ou nas atribuições Dinâmicas de qualquer regra.

{% hint style="info" %}
Atualmente, não é suportado adicionar extensões personalizadas de certificado aos perfis SCEP em muitos sistemas MDM, incluindo Microsoft Intune e Jamf Pro.

Por isso, recomendamos utilizar o Nome do Subject do Certificado em vez disso para [atribuir VLANs dinamicamente](https://docs.radiusaas.com/admin-portal/settings/rules#vlan-assignment).

## 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.radiusaas.com/pt/portal-de-administracao/acesso-e-regras/rules/extensoes-de-certificado.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.
