没有主目录的用户的SSH公钥

Question

我正在运行Mac OS X Leopard Server,我创建了一个新用户,但没有为该用户指定主目录.是否可以让该用户使用公钥进行身份验证？

我知道当用户确实有一个主目录时,它会进入~/.ssh/authorized_keys

我不想为这个用户创建一个主目录,因为我的理解是它允许他们在给定物理访问时登录.

更新:我需要允许此用户仅进行安全FTP连接.将登录Shell设置为/bin/false/阻止它们远程连接.

您必须编辑/etc/ssh/sshd_config它或在您的机器上的位置并更改AuthorizedKeysFile设置.

文档说:

 AuthorizedKeysFile
         Specifies the file that contains the public keys that can be used
         for user authentication.  AuthorizedKeysFile may contain tokens of
         the form %T which are substituted during connection setup.  The fol-
         lowing tokens are defined: %% is replaced by a literal '%', %h is
         replaced by the home directory of the user being authenticated, and
         %u is replaced by the username of that user.  After expansion,
         AuthorizedKeysFile is taken to be an absolute path or one relative
         to the user's home directory.  The default is
         ``.ssh/authorized_keys''.

但是,为什么没有家庭的用户(可登录)？
