不支持 mount.cifs 操作，但 smbclient 按預期連接

在帶有版本的 Debian 8.2 上安裝 OSX 10.9.5 共享時mount.cifs。6.4：

mount error(95): Operation not supported

憑證不是問題。我可以通過smbclient. Mount 正確地從憑證文件中讀取域和使用者名。我以root身份執行，所以希望不是權限問題。

我能找到的唯一區別是/var/log/system.log文件共享主機上報告的標誌。使用列表訪問mount.cifs沒有標誌，smbclient列出了一些。但是mount.cifs它正在另一台機器（archlinux）上工作，也沒有標誌。

# smb client works fine
smbclient \\\\arnold\\T800 -A ~ni_tools/passwd/arnold 
  Domain=[ARNOLD] OS=[Darwin] Server=[@(#)PROGRAM:smbd  PROJECT:smbx-276.92.2]
  smb: \> 

# mount
sudo mount -t cifs //arnold/T800 test -o credentials=~ni_tools/passwd/arnold,iocharset=utf8,uid=1000,gid=1000,rw -vv
 domain=ARNOLD
 mount.cifs kernel mount options: ip=157.229.27.130,unc=\\arnold\T800,iocharset=utf8,uid=1000,gid=1000,user=lncd,,domain=ARNOLD,pass=********
 mount error(95): Operation not supported
 Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
