このドキュメントでは、Password Authentication Protocol(PAP)または Challenge Handshake Authentication Protocol(CHAP)を使用しているときに、RADIUS に共通する問題をデバッグする方法について詳しく説明します。 Microsoft Windows 95、Windows NT、Windows 98、Windows 2000 に共通する PC の設定に加えて、設定例および適切なデバッグ例と不適切なデバッグ例も示します。
ドキュメント表記の詳細は、『シスコ テクニカル ティップスの表記法』を参照してください。
このドキュメントに関しては個別の前提条件はありません。
このドキュメントの情報は CiscoIOS® ソフトウェア リリース 11.2 以降に基づいています。
このマニュアルの情報は、特定のラボ環境に置かれたデバイスに基づいて作成されました。このドキュメントで使用するすべてのデバイスは、初期(デフォルト)設定の状態から起動しています。実稼動中のネットワークで作業をしている場合、実際にコマンドを使用する前に、その潜在的な影響について理解しておく必要があります。
次に示す手順に従ってください。
[ダイヤルアップネットワーク]ウィンドウで接続名を選択し、[ファイル] > [プロパティ]を選択します。
[Server Type] タブで、[Type of Dial-up Server] の下にある [Require Encrypted Password] ボックスがチェックされているかどうかを確認します。
このボックスがチェックされている場合、PC では、CHAP 認証だけが受け入れられていることを意味します。
このボックスがチェックされていない場合、PC では PAP 認証または CHAP 認証が受け入れられていることを意味します。
次に示す手順に従ってください。
[ダイヤルアップネットワーク]ウィンドウで接続名を選択し、[ファイル] > [プロパティ]を選択します。
Security タブで、設定を確認します。
Accept any authentication including clear text ボックスがチェックされている場合、PC では PAP および CHAP が受け入れられていることを意味します。
[Accept only encrypted authentication] ボックスがチェックされている場合、PC では CHAP 認証だけが受け入れられます。
次に示す手順に従ってください。
Dial-Up Networking ウィンドウで、接続名を選択してから、Properties を選択します。
Server Types タブで、Advanced Options エリアの設定を確認します。
Require encrypted password ボックスがチェックされていない場合、PC では PAP 認証または CHAP 認証が受け入れられていることを意味します。
Require encrypted password ボックスがチェックされている場合、PC では CHAP 認証だけが受け入れられていることを意味します。
次に示す手順に従ってください。
Network and Dial-Up Connections で、接続名を選択してから、Properties を選択します。
[Security]タブで、[Advanced] > [Settings] > [Allow these protocols]領域の設定を確認します。
[Unencrypted password (PAP)] ボックスがチェックされている場合、PC では PAP が受け入れられます。
[Challenge Handshake Authentication Protocol (CHAP)] ボックスがチェックされている場合、PC では、RFC 1994 の規定による CHAP が受け入れられます。
[Microsoft CHAP (MS-CHAP)] ボックスがチェックされている場合、PC では MS-CHAP バージョン 1 が受け入れられますが、RFC 1994 の規定による CHAP は受け入れられません。
