[Samba] More strangeness with ZFS and Samba

  A new problem now.  Running Samba 3.5.4, on Solaris 10 with zfs.

Issue with Microsoft Office 2007:
User opens up a .xlsx, then closes the file (Not Excel).
Then user reopens the .xlsx file and now Excel says the file is 
read-only.  But permissions on the file have not changed!
Only fix is to exit out of Excel and restart, then user can open that 
file just fine.

The issue also looks to be tied to how big the file is.  Small .xlsx 
files do not exhibit this behavior. But files over 500K does it all the 
time. Time doesn't matter either, user can close the file and then come 
back to open it an hour later and it will still say read-only.

Here is my conf file. issue is with all shares, I'm including just one 
atmos share below:

     workgroup = ENGR_DOM
     server string = Samba Server
     interfaces = e1000g0, lo0
     bind interfaces only = Yes
     security = DOMAIN
     passdb backend = smbpasswd
     client NTLMv2 auth = Yes
     map untrusted to domain = Yes
     log level = 1
     log file = /var/log/samba/logs/log.%m
     name resolve order = host bcast
     unix extensions = No
     max open files = 10000
     load printers = No
     domain master = No
     dns proxy = No
     lock spin time = 3
     veto oplock files = 
     strict locking = No

     comment = ATMOS
     path = /XKA2/academic/Atmos
     valid users = +Atmosfac
     force group = Atmosfac
     read only = No
     create mask = 0770
     force create mode = 0770
     security mask = 0770
     directory mask = 02770
     inherit permissions = Yes
     inherit acls = Yes
     nt acl support = No
     map archive = No
     map readonly = permissions
     store dos attributes = Yes
     vfs objects = zfsacl
     nfs4:mode = special
     nfs4:acedup = merge
