Azure confidential ledger で証明書ベースのユーザーを管理する

証明書ベースのユーザーの場合、ユーザー ID は PEM 証明書のフィンガープリントです。 管理者特権を持つユーザーは、confidential ledger のユーザーを管理できます。 使用可能なロールは、閲覧者 (読み取り専用)、共同作成者 (読み取りと書き込み)、管理者 (読み取り、書き込み、および管理ユーザー) です。

ユーザーを管理するには、次のクライアント ライブラリを使うことができます:

Azure へのサインイン

Azure CLI az login コマンドまたは Azure PowerShell Connect-AzAccount コマンドレットを使用して Azure にサインインします。

az login

CLI または PowerShell で既定のブラウザーを開くことができる場合、ブラウザが開き、Azure サインイン ページが読み込まれます。 そうでない場合は、https://aka.ms/devicelogin を開き、ターミナルに表示されている認証コードを入力します。

メッセージが表示されたら、ブラウザーでアカウントの資格情報を使用してサインインします。

Azure portal から confidential ledger の名前と ID サービス URI を取得します。これには、ユーザーを管理するためのクライアントの作成が必要になります。 この図は、Azure portal の適切なプロパティを示しています。

Azure portal のレジャー プロパティを示すスクリーンショット。

次のコード スニペットの contosohttps://contoso.confidential-ledger.azure.com のインスタンスを、Azure portal のそれぞれの値に置き換えます。
