How to mount CIFS shares on a system with samba4 packages installed?

Issue

• Mounting a CIFS share on a system with installed samba4* packages gives the following error message:

  # mount -t cifs -o username=sambatest,passwd=sambatest //sambatest/test /mnt
  mount: wrong fs type, bad option, bad superblock on //sambatest/test,
         missing codepage or helper program, or other error
         (for several filesystems (e.g. nfs, cifs) you might
         need a /sbin/mount.<type> helper program)
         In some cases useful info is found in syslog - try
         dmesg | tail  or so
  

• cifs-utils installation fails on a system which has samba4* packages installed, with dependency errors.
