我遇到了一个奇怪的问题：我可以使用 Linux 机器连接到 Samba 服务器（在 Mac 上），smbclient但无法使用以下方式挂载 Samba 共享：CIFS
smbclient有效的命令是：
smbclient -U MYUSERNAME -W X.YYY.ZZ -m SMB2 -d 3 //SERVER/LEEF

我尝试了以下挂载命令
sudo mount -t cifs //SERVER/LEEF /mnt/LEEF_IEU/ -o username=MYUSERNAME,domain=X.YYY.ZZ,vers=2.0
但我得到了
mount error(95): Operation not supported
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
和所有其他vers=我得到
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
我在这里不知所措，感觉我忽略了显而易见的东西。有什么建议可以告诉我这里发生了什么，以及我如何安装 samba 共享（不一定是 cifs）？
谢谢。
