[Samba] Can't create file.

[jeff sacksteder]

I can authenticate at the smb level, but there's something wrong at
the posix level when I try to edit or create files. I am always denied
access regardless of how loose the file/directory permissions are.
This is what I am seeing in the logs -

other than the mode of the directory, what would cause this to return
access_denied?
