我使用 ipa-client-install 配置了一个客户端（rinaldo），当我 ssh 进入它时，它说Could not chdir to home directory /home/zaira/smith: Permission denied我最终进入目录/。
$ ssh -v rinaldo

当我 ssh 到 rinaldo 时，我看到了这个：
debug1: Unspecified GSS failure. Minor code may provide more information
Decrypt integrity check failed
什么会导致出现此消息？
当我登录另一个客户端（ernani）时，我没有看到它：

我的 中有以下内容/etc/fstab：
zaira2:/home/zaira /home/zaira nfs4 defaults,auto,sec=krb5i,rw,proto=tcp,port=2049 0 0
一旦/home/zaira安装完毕，
-bash-4.3$ ll /home/
ls: cannot access /home/zaira: Permission denied
total 0
d????????? ? ? ? ? ? zaira
所以，当然不可能 chdir 到主目录。
