samba - Mar 2016 - Map hidden can only work if create mask includes octal 01 (S_IXOTH)

This is probably something simple, but I couldn't find the problem addressed
in this maillist.

I've upgraded to Samba 4.x from Samba 3.x.  I'm just using this for
"classic" sharing, not
AD/DC.  I'm getting an error when I run testparm which I didn't with the
previous version (or
didn't notice). 

"Invalid combination of parameters for service public. Map hidden can only
work if create mask
includes octal 01 (S_IXOTH)."

this section is:

[public]
        path = /mnt/RAID/public
        read only = No
        create mask = 0660
        force create mode = 0660
        directory mask = 0771
        guest only = Yes
        guest ok = Yes
        hide files = /Outlook/outlook/~*/
        veto oplock files = /OfficeCalendar.pst/
        map hidden = Yes
        
Can someone test me what I need to do to fix this?

Well, to be honest the error message is telling you what to do :-)

If you read 'man smb.conf' under the heading 'map hidden (S)'
you will
find this:

            Note that this requires the create mask to be set such that the
            world execute bit is not masked out (i.e. it must include 
001). See
            the parameter create mask for details.

As you are also using 'force create mode' I would suggest you go and 
read the smb.conf manpage, as all three settings affect each other.
