authentication - Tomcat 8 基本認証

Question

Apache Tomcat で BASIC 認証を実装しようとしていますが、奇妙な問題が発生します。

ボックスにアクセスするhttp://localhost:8080.と、ユーザー名とパスワードを入力できるように表示されます。問題は、認証が成功しないことがわかり、ボックスが何度も表示されることです。

以下は私の設定です：

/WEB-INF/web.xml

ただのウェルカムファイルです。

私は何を間違えましたか？または私は何を逃したのですか？私はこれについて多くを検索しましたが、まだ解決策を見つけることができません。私はstackoverflowが初めてです。私の質問が明確であることを願っています。誰かが助けてくれることを願っています!
