** 考え方 [#d8a71a9f]
- mvc (=kgb.hmuna.com) には公式なサーバー証明書を導入済み
- mvc のログイン認証は local IP ゾーン（VPN 接続を含む）は認証なし、その他は One Time パスワード認証を要求
- これに加えクライアント認証を導入し、認証済クライアントはパスワード無しで接続できるようにしたい
- 発行済のサーバー証明書からクライアント証明書を発行する方法が無い（CoMoDo には別にクライアント認証オプションあり）
-- [[Comodo Client Certificates:https://comodosslstore.com/email-identity/client-certificate]]
- 一方でオレオレ認証ベースでのクライアント証明書を発行する事例は多数参考記事がある
-- [[オレオレ認証局でのクライアント証明書の作り方(sha256):https://glodia.jp/blog/%E3%82%AF%E3%83%A9%E3%82%A4%E3%82%A2%E3%83%B3%E3%83%88%E8%A8%BC%E6%98%8E%E6%9B%B8%E3%81%AE%E4%BD%9C%E3%82%8A%E6%96%B9]]

- （方針）&color(red){クライアント証明書については、公式サーバー証明書とは別にオレオレ認証局で作り Apache2 に組み込んで動作確認する};
-- この考え方（＝サーバー証明書とクライアント証明書は別の認証局を使う）で正しいことを CyberTrust に確認した。
