samba - Nov 2004 - winbind use default domain

Hello Everyone
I have set winbind use default domain, but am getting this in the log:

[2004/11/10 15:16:33, 2] smbd/close.c:close_normal_file(262)
  MYDOMAIN+Debbie closed file Sage10/ACCDATA/SALINDEX.DTA (numopen=1)
[2004/11/10 15:16:34, 2] smbd/open.c:open_file(245)
  Debbie opened file Sage10/ACCDATA/NOMINAL.DTA read=Yes write=No 
(numopen=2)

Not a big deal, but any ideas why it is using MYDOMAIN+user for open and 
just user for close?

Samba 3.0.7 on SuSE 9.0

Thanks,
H
