更新 sudoers 后用户仍然无权访问 sudo

Question

我在通过 /etc/sudoers 文件将用户添加到 sudoers 列表时遇到问题。

$ whoami
iain

然后他们说我疯了！

$ which visudo
/usr/sbin/visudo

$ ls -la /usr/sbin/visudo
---x--x--x  1 root  wheel  186768 23 Jun  2009 /usr/sbin/visudo


$ sudo su -
Password:
macbook:~ root# whoami
root
macbook:~ root# visudo

该文件在 vi 中打开：

# this line is the one I added to sudoers
# I gave ALL as access to try and get this to work
# it's the same setting as my account, which works.
%yvonne         ALL=(ALL) ALL

我保存文件。它在这里显示“未更改”，因为我已经完成了。

visudo: /etc/sudoers.tmp unchanged
macbook:~ root# logout

以 yvonne 身份登录...

$ sudo su - yvonne

yvonne@87 02/08/2013 19:34 $ whoami
yvonne

尝试通过sudo以下方式运行任何东西：

yvonne@88 02/08/2013 19:34 $ sudo ls

WARNING: Improper use of the sudo command could lead to data loss

To proceed, enter your password, or type Ctrl-C to abort.

Password:
**yvonne is not in the sudoers file.  This incident will be reported.**

我很困惑，谁能给我任何帮助或见解，以便我可以授予yvonne帐户访问权限sudo？将不胜感激。

%是 sudoers 中的组赋值运算符。我认为您希望该行阅读：

yvonne         ALL=(ALL) ALL
