# Access settings

The Theme settings described below apply to Parallels Client for all available platforms.

* **Override authentication domain**: Allows you to specify a domain name that will be passed to Parallels Client, so users don't have to enter it manually. This setting overrides the domain name setting in **Connection** > **Authentication**. For more information, see [**Allowing users to change domain password**](/landing/ras-admin-guide/parallels-ras-21-administrators-guide/connection-and-authentication-settings/allowing-users-to-change-domain-password.md).
* **Limit access to this Theme to members of these Active Directory groups:** If this option is cleared, any Parallels RAS user can access the Theme if they know its URL. To limit access to a particular group (or groups), select this option and then click **Tasks** > **Add** (or click the **\[+]** icon) and select the desired group(s).
* **MFA provider:** Select an MFA provider for the Theme.
* **(Default theme only) Allow gateway tunneling connections**: Allow gateway tunneling connections for the deafult theme.

## 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.parallels.com/landing/ras-admin-guide/parallels-ras-21-administrators-guide/parallels-web-client-and-user-portal/configure-themes/access-settings.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.
