# SAML SSO 認証

Parallels RAS 17.1 以降では、SAML-P 認証メカニズムがサポートされています。SAML-P は XML ベースの認証方式であり、ローカルの ID データベースを共有することなくユーザー認証を行うことで、異なる組織間でシングルサインオン（SSO）機能を実現します。

SAML SSO プロセスの一環として、新しい RAS 登録サーバーは Microsoft 認証局 (CA) と通信し、ユーザーに代わってデジタル証明書を要求、登録、および管理することで、ユーザーが Active Directory の資格情報を入力することなく認証を完了させます。 サービスプロバイダーや複数の子会社を持つ企業は、独自の内部ID管理ソリューションや複雑なドメイン／フォレスト間の信頼関係を維持する必要がなくなります。サードパーティのIDプロバイダーとの統合により、顧客やパートナーはエンドユーザーに真のSSO体験を提供できるようになります。

## 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.parallels.com/landing/ras-admin-guide/v22-ja-jp/saml-sso-ren-zheng.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.
