突然、正しいパスワード（greeter＆tty）でログインできません

これは、他のパスワード関連の質問の複製である可能性がありますが、なんとなく風変わりです。

buntu 12.1システムに3つのアカウントがあります（1人の標準と2人の管理者）。管理者アカウントの1つが私の主な開発アカウントであり、突然昨日の前に、奇妙な振る舞いをし始めました（最新の更新-カーネルなどから）：

  • グリーター段階でパスワードを入力すると、すぐに「間違ったパスワード」が返されます。チェックもしません。 （NB：パスワードは完全に正しいです）
  • [〜＃〜] tty [〜＃〜]でログインできません。ログイン名とパスワードを入力すると、ログイン名の入力を求めるプロンプトがすぐに表示されます...このアカウントを認証するパスが誤ってロックされたか、アクセスが封印されたようです。

2つ目の管理者アカウントでログインし、問題のあるアカウントのパスワードを変更しましたが、うまくいきませんでした。パスワードを元の値に戻し、アカウントを自動ログインに設定しました。再起動し、実際にアカウントがログインしました。しかし、異常は残ります：

  • I root権限アクションを実行できません（Sudoおよびgksudo）。パスワードを入力しても、何も起こりません。パスワードが受け入れられるのは、画面がロックされているときと、ロックを解除するためにパスワードの入力を求められるときだけです。

ホームフォルダーの所有権を確認しましたが、問題ありません。いくつかの助けは非常にありがたいです。

つまり、lightdmを介してログインできない-Sudo、gksudo、pkexecが成功しない-suコマンドが失敗する-Sudoコマンドに誤ったパスワードを指定すると、チェックが行われ、「パスワードが正しくありません」が返されます。正しいパスワードを入力すると、何も返されません。 -自動ログインすると、パスワードキーリングが受け入れられます。 -画面のロックを解除すると、パスワードが受け入れられます。

  • 私はすでにパスワードを変更し、ユーザー名が（Sudo、admin、adm、...）のようなグループに属しているかどうかを確認しました。

問題が解決しました。

問題が解決する前に私が実行したアクションは次のとおりです。

  • Sudo ppa-purge ppa：gnome3-team/gnome3（nautilusなどのサポートされているgnomeパッケージに戻すために）

  • ディレクトリの作成：/ var/lib/sambaおよび自分自身をsambaパスワードに追加するdatabse（Sudo mkdir -p/var/lib/samba && Sudo smbpasswd -a myusername

  • Sudo pam-auth-update（すべての認証モジュールがすでに選択されているので、私は大丈夫と言っただけです）。

私はやったchmod 555を、問題の原因となったホームフォルダに追加します。解決策は、他の誰かのラップトップを使用してアクセス許可を元に戻すことです。

ssh (your laptop username)@(your IP)
cd ..
chmod 777 (your username on laptop)
