Ubuntu
突然，我無法使用正確的密碼登錄（greeter & tty）
這可能是其他密碼相關問題的重複，但它有點古怪。
我的Ubuntu 12.10系統中有 3 個帳戶（一個標準帳戶和兩個管理員帳戶）。管理員帳戶之一是我的主要開發帳戶，突然在昨天之前，它開始表現得很奇怪（因為最新的更新 - 核心和其他：
- 在歡迎階段，當我輸入密碼時，它會立即返回“密碼錯誤”。它甚至不檢查。（注：密碼絕對正確）
- 在TTY，無法登錄，一旦我輸入我的登錄名和密碼，它會立即重新提示我輸入登錄名……感覺驗證此帳戶的路徑被意外鎖定或訪問密封。
我使用我的第二個管理員帳戶登錄並更改了麻煩帳戶的密碼，但沒有運氣，將密碼恢復為原始值並將帳戶設置為自動登錄。重新啟動，然後，確實該帳戶已登錄。但是，異常仍然存在：
- 我無法執行 root 權限操作 (sudo & gksudo)。輸入密碼後，什麼也沒有發生。唯一接受密碼的情況是螢幕被鎖定並提示我輸入密碼以解鎖它。
我檢查了我的主文件夾的所有權，沒關係。非常感謝一些幫助。
總結一下： - 無法通過 lightdm 登錄 - sudo、gksudo 和 pkexec 不成功 - su 命令失敗 - 如果我為 sudo 命令提供的密碼不正確，它會檢查並返回“密碼不正確”，但如果我提供正確的密碼，它不會返回任何內容。- 我自動登錄時接受密碼密鑰環。- 當我解鎖螢幕時，密碼被接受。
- 我已經更改了密碼並檢查了我的使用者名是否屬於（sudo、admin、adm、….）之類的組。

在 x-2 日誌中，使用者 hanine 的身份驗證返回碼為 19（失敗），而 admin 的身份驗證返回碼為 0（成功）。
問題解決了。
以下是我在問題解決之前執行的操作：
- sudo ppa-purge ppa:gnome3-team/gnome3（為了恢復到支持的 gnome 包，如 nautilus 等）
- 創建目錄：/var/lib/samba 並將自己添加到 samba 密碼數據庫（sudo mkdir -p /var/lib/samba && sudo smbpasswd -a myusername
- sudo pam-auth-update（所有的身份驗證模組都已被選中，所以我只是點擊好了）。
