r22732: - Testing of libsmbclient against Vista revealed what is likely a bug in

  Vista.  Vista provides a plethora of kludges to simulate older versions of
  Windows.  The kludges are in the form of shortcuts (or more likely symbolic
  links, but I don't know enough about Vista to determine that definitively)
  and in most cases, attempts to access them get back an "access denied"
  error.  On one particular folder, however, "<share>/Users/All Users", it
  returns an unknown (to ethereal and the Samba3 code) NT status code:
  0x8000002d.  Although this code does not have a high byte of 0xc0 indicating
  that it is an error, it appears to be an alternate form of "access denied".

  Without this patch, libsmbclient times out on an attempt to enumerate that
  folder rather than returning an error to the caller.  This patch corrects
  that problem.
(This used to be commit cc0cd3a12f76b8cd711e3165d4cfe920552f256d)
