在 Kerberized Linux box 上添加本地用户/密码

Question

现在，如果我尝试添加不在大学 Kerberos 领域中的非系统用户，无论如何都会提示我输入 Kerberos 密码。显然没有密码需要输入，所以我直接回车看看：

passwd: Authentication token manipulation error
passwd: password unchanged

键入passwd newuser具有相同消息的相同问题。

我尝试使用pwconv，希望只需要一个影子条目，但它没有任何改变。

我希望能够添加一个不在域中的本地用户并为他们提供本地密码，而不必担心 Kerberos。

我在 Ubuntu 10.04 上。这是我的/etc/pam.d/common-*文件（Ubuntupam-auth-update软件包生成的默认值）：

# prime the stack with a positive return value if there isn't one already;
# this avoids us returning an error just because nothing sets a success code
# since the modules above will each just jump around

通过 pam-auth-update 命令临时调整

1. 您可以使用pam-auth-update. 所以它看起来像这样：
   [ ] Kerberos authentication
2. 然后您可以添加用户/更改密码。
3. 然后pam-auth-update在完成后重新激活 Kerberos 。所以它看起来像这样：
   [*] Kerberos authentication
