# ユーザー認証

RAS マルチテナントアーキテクチャのユーザー認証は、テナントファームで稼働している RAS Connection Broker が行います。Connection Broker は、共有の RAS Secure Gateway によってランダムに選択されます。利用可能な Connection Broker がない場合は、その趣旨のマークが設定され、一定の時間、同じ共有ゲートウェイからの通信が行われなくなります。ゲートウェイは、周期的に Connection Broker の状況を確認し、利用可能になったらすぐに通信を再開します。

# 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 dynamically by asking a question.

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

```
GET https://docs.parallels.com/landing/ras-admin-guide/v20-ja-jp/ras-nomaruchitenantokitekucha/tenantoburktotenantono/yz.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 `build a script that syncs our docs to a CMS` 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.
