cifs 所需密钥不可用

我已经使用 PowerBroker IS 加入了 zentyal 域（AD 域），并且我希望它在远程用户登录时挂载我的远程主目录。这是 PBIS 的配置：

Local_SkeletonDirs "/etc/skel"

LsassAutostart true
EventlogAutostart true

据我了解，只要设置了 RemoteHomeDirTemplate，它就应该安装，但问题是，它没有安装。

因此我想尝试找到一个用户，看看它的主目录路径是如何显示的（如果有的话）：

# /opt/pbis/bin/find-objects --user tomas

所以它有一个主目录路径，适用于 unix 和 windows，所以我不知道可能是什么问题。

我/var/log/messages发现了一些错误：

Dec  4 12:55:30 winbind lsass: [lsass] Failed mount of //nyborg.MOSEK.ZENTYAL/tomas on /home/tomas with data sec=krb5i,[email protected],uid=1588593748,gid=1588593153,cruid=1588593748,ip=172.16.0.5, error 40188 (errno 126)

Dec  4 12:55:30 winbind kernel: CIFS VFS: cifs_mount failed w/return code = -126

我尝试手动运行该命令并收到正确的错误消息：错误 126：

#mount -t cifs -o sec=krb5i,[email protected],uid=1588593748,gid=1588592152,cruid=1588593748,ip=172.16.0.5 //nyborg.MOSEK.ZENTYAL/tomas /home/tomas
mount error(126): Required key not available
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

我检查了一下，我有一个 krb 票：

#klist
Ticket cache: KEYRING:persistent:0:0
Default principal: [email protected]

Valid starting       Expires              Service principal
12/09/2014 12:20:36  12/09/2014 22:20:36  krbtgt/[email protected]
    renew until 12/16/2014 12:20:33

好的，我发现如果我向用户提交了一张票，我就可以手动安装它。如果我以 tomas 用户身份进入，PBIS会获取 cifskinit [email protected]error 16

那么什么可以解决这个问题呢？

编辑：

我尝试安装新版本的 pbis（PBIS Open 8.2.1），现在收到的错误不同了：

答案1

我认为我已经找到了您的问题的答案，请在此处查看我自己的问题：

Powerbroker Open：无法自动挂载 CIFS 共享，Kerberos 票证在哪​​里？

CentOS 7 使用 systemd，PBIS 服务配置为使用私有“tmp”文件夹。不幸的是，这会导致在错误的目录中创建 Kerberos 票证（它是在 /tmp/systemd-private-xxx 而不是 /tmp 中生成的）。我编辑了服务配置lwsmd.service并设置PrivateTmp=no。现在一切正常...

答案2

我昨天收到了同样的错误消息；就我而言，这是一个通过与 AD 服务器相同的 DNS 寻址服务器（在 DNS 中有多个名称）的问题。
