このドキュメントの情報は、特定のラボ環境にある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。対象のネットワークが実稼働中である場合には、どのようなコマンドについても、その潜在的な影響について確実に理解しておく必要があります。

問題

VPNユーザは、RADIUSサーバによって認証および認可されるように設定されます。ASRの設定を次に示します。

aaa group server radius ACS-Rad
 server-private 10.88.171.27 key cisco123
 ip vrf forwarding Mgmt-intf
aaa group server tacacs+ ACS-Tac
 server-private 10.88.171.27 key cisco123
 ip vrf forwarding Mgmt-intf
aaa authentication login VPN_Client group ACS-Rad
aaa authentication login login_local local
aaa authorization network VPN_Client group ACS-Rad 
aaa authorization network login_local local 
aaa accounting network VPN_Client start-stop group ACS-Rad
aaa accounting network login_local start-stop group ACS-Rad
aaa session-id common

ただし、認証を試みるたびに、資格情報の入力を求められることはありません。クライアントでは、次のエラーメッセージがログメッセージに表示されます。

Unable to establish Phase 1 SA with server "X.X.X.X" because of
"DEL_REASON_PEER_NOT_RESPONDING"

ASR上のデバッグは、VPNグループ名が認証の試行にUser-Nameとして使用されていることを示します。

注：ただし、ローカル認証が設定されている場合は、すべて正常に動作します。

解決方法

報告された動作は予期されており、バグではありません。リモートアクセスVPNには2つの認証プロセスがあります。

ユーザが接続するトンネルの事前共有キー認証。
個々のユーザを認証するXAUTH。

XAUTHはフェーズ1.5であり、事前共有キー認証がフェーズ1で成功した後にのみ発生します。パスワードのユーザプロンプトが表示されない理由は、フェーズ1がまだ完了していないためです。デバッグで送信されるユーザ名は、実際にはフェーズ1事前共有キー認証に使用されます。

ローカル認可とRADIUS認可

ローカル認証が設定されると、VPNヘッドエンドはグループ設定で設定されたキー値をピックアップして、フェーズ1を完了します。これにより、フェーズ1が完了し、ルータはXAUTHに進むことができます。

ルータがRADIUSサーバに対して認可するように設定されている場合、キーを取得するには（事前共有認証の場合）、RADIUSサーバに対してアクセス要求クエリを実行する必要があるため、機能しません。ただし、アクセス要求クエリではRADIUSAに送信するユーザ名が必要です。XAUTHはまだ実行されていないため、クライアントユーザ名を使用することはできません。この場合、代わりにグループ名をユーザー名として使用します。ただし、RADIUSサーバは、そのIDによってユーザを確認するように設定されていないため、要求を拒否します。このため、フェーズ1は完了せず、ユーザはクレデンシャルの入力を求められることはありません。

RADIUS サーバの設定

RADIUSサーバを設定するには、次の手順を実行します。

Groupnameユーザーを構成します。
すべての属性値(AV)ペアを付与するように認可プロファイルを設定します。
接続を許可し、そのプロファイルを使用するようにアクセスポリシーを設定します。

トラブルシュート

アウトプットインタープリタツール（登録ユーザ専用）は、特定の show コマンドをサポートしています。show コマンドの出力の分析を表示するには、Output Interpreter Tool を使用します。

注：debug コマンドを使用する前に、「デバッグコマンドの重要な情報」を参照してください。

VPNヘッドエンドで次のデバッグが有効になります。

Internet Security Association and Key Management Protocol(ISAKMP)デバッグ
