File ownership being changed to root:wheel ownership after copying to samba server

[Troy]

A very strange problem just started happening with Samba after I 
upgraded to version samba34-3.4.9 on FreeBSD 8.0-STABLE.

Let's say my username is foobar.  I copy a file named To Fix.txt from a 
windows desktop machine to a samba share.

In the log it shows the following:

[2010/10/28 00:53:16,  2] lib/access.c:406(check_access)
   Allowed connection from 172.16.0.5 (172.16.0.5)
[2010/10/28 00:53:24,  2] smbd/open.c:580(open_file)
   foobar opened file Working/To Fix.txt read=Yes write=Yes (numopen=2)
[2010/10/28 00:53:24,  2] smbd/close.c:612(close_normal_file)
   foobar closed file Working/To Fix.txt (numopen=1) NT_STATUS_OK

Then when I look at the owner:group of the file that was just copied it 
shows:

-rwxr-xr-x   1 root      wheel        1422 Oct 27 16:07 To Fix.txt*

I cannot figure out why the file is owned by root:wheel when it should 
be foobar:foobar.

No sticky bit is set on the directory and the parent directory 
permissions are owned by the user foobar:wheel

drwxr-xr-x   6 foobar  wheel   512 Oct 28 00:53 Working/

This is only happening when I copy over files using Samba.  Anyone have 
any ideas?

Thanks
