# Build cifs-utils in a container and copy it into /tmp on the host.
$docker run -t -i -v /tmp:/host_tmp fedora /bin/bash
# On the container bash prompt
yum groupinstall -y "Development Tools" "Development Libraries"
yum install -y tar
yum install -y bzip2
curl http://ftp.samba.org/pub/linux-cifs/cifs-utils/cifs-utils-6.3.tar.bz2 | bunzip2 -c - | tar -xvf -
cd cifs-utils-6.3/
./configure && make
cp mount.cifs /host_tmp/
exit
#back at the  host
$ sudo mkdir /mnt/foo
$ sudo /tmp/mount.cifs //198.51.100.23/foo /mnt/foo -o domain=zzz,username=xxx,password=yyy
$ mount | grep /mnt/foo

I had to replace http://ftp.samba.org/pub/linux-cifs/cifs-utils/cifs-utils-6.3.tar.bz2 for https://download.samba.org/pub/linux-cifs/cifs-utils/cifs-utils-6.3.tar.bz2 to work.

Great job

I got "mount error(95): Operation not supported". Would you please help me to fix it?

I figured it out! I have to add "vers=2.0" to work, as follows:
sudo /tmp/mount.cifs //198.51.100.23/foo /mnt/foo -o domain=zzz,username=xxx,password=yyy,vers=2\.0

Thanks for your help! However, I don't think these steps need to be performed any longer under the latest version of CoreOS.

I was able to perform a mount -t cifs <address> -o sec=krb6,vers=3.0 just fine out of box once connected to my domain via KRB5 :)

$ which mount.cifs
/usr/sbin/mount.cifs
