Fix bug #10097 - MacOSX 10.9 will not follow path-based DFS referrals handed out by Samba.
Windows overloads the EA Length field in the DIRECTORY INFO leves of FIND FIRST/FIND NEXT.
This field indicates either the REPARSE_TAG if the file/folder has a reparse proint or
the EA Length if it has EAs, and is the fundamental reason you cannot have both on a
file or folder.
