[Samba] zfs permissions

[Tom Jermy]

Hello,

I'm using Samba Version 4.0.15-SerNet-RedHat-7.el6 (AD DC)
and zfs-0.6.2-1.el6.x86_64.

I cannot change permissions on files from either Windows ('Access Denied')
or the samba-tool on shares from local zfs mounts:

# samba-tool ntacl set 'O:LAG:S-1-22-2-0D:PAI(A;OICI;0x001301bf;;;WD)'
CompanyName/ Company/

fset_nt_acl_no_snum: fset_nt_acl returned NT_STATUS_ACCESS_DENIED.
ERROR(runtime): uncaught exception - (-1073741790, 'Access denied')
  File "/usr/lib64/python2.6/site-packages/samba/netcmd/__init__.py", line
175, in _run
    return self.run(*args, **kwargs)
  File "/usr/lib64/python2.6/site-packages/samba/netcmd/ntacl.py", line 90,
in run
    setntacl(lp, file, acl, str(domain_sid), xattr_backend, eadb_file,
use_ntvfs=use_ntvfs)
  File "/usr/lib64/python2.6/site-packages/samba/ntacls.py", line 154, in
setntacl
    smbd.set_nt_acl(file, security.SECINFO_OWNER | security.SECINFO_GROUP |
security.SECINFO_DACL | security.SECINFO_SACL, sd)

I cannot see where I am going wrong. I have zfs set
aclinheritance=passthrough-x, tried xattr on/off/sa/dir ...

Perhaps this belongs on the zfs list but would appreciate any feedback if
there are folk out there who have encountered this / not encountered this.

Thank you
