I just gave this a try with the standard64 14.3.0 image and it worked with
the below smb.conf file:

[global]
   workgroup = MYGROUP
   server string = Samba %v (%h)
   security = user
   load printers = yes
   unix extensions = no

[homes]
   comment = Home Directories
   browseable = no
   writable = yes

[myshare]
   comment = MyShare
   path = /zones/2247fa19-211f-4f62-a781-4bbf50105f59/data/test
   public = yes
   writable = yes
   printable = no
   vfs objects = shadow_copy2
   shadow: snapdir = .zfs/snapshot
   shadow: sort = desc
   shadow: format = %Y%m%d-%H%M%S
   wide links = yes


I was taking snapshots with the command:

zfs snapshot zones/2247fa19-211f-4f62-a781-4bbf50105f59/data/test@`date -u
+%Y%m%d-%H%M%S`


One troubleshooting tip is to run with a higher debug level.  As an example
with a debug level of 3 and without the unix extensions option it was
showing access denied errors.  It also shows the paths it is trying to
access so you can verify the date mappings are working correctly.  Here is
a sample of what it looks like:

check_reduced_name [@GMT-2015.02.12-13.22.04/test2/asdf]
[/zones/2247fa19-211f-4f62-a781-4bbf50105f59/data/test]
check_reduced_name: Bad access attempt: @GMT-2015.02.12-13.22.04/test2/asdf
is a symlink outside the share path
conn_rootdir
=/zones/2247fa19-211f-4f62-a781-4bbf50105f59/data/test/.zfs/snapshot/@GMT-2015.02.12-13.22.04/
resolved_name=/zones/2247fa19-211f-4f62-a781-4bbf50105f59/data/test/.zfs/snapshot/20150212-132204/test2/asdf
filename_convert: check_name failed for name
@GMT-2015.02.12-13.22.04/test2/asdf with NT_STATUS_ACCESS_DENIED
