/**
  * Given an enumeration of candidates, check whether each

  * Each item is a Binding and the following is used to get its
  * attributes for used by the filter:
  *
  *   ((DirContext)item.getObject()).getAttributes("").
  * If item.getObject() is not an DirContext, the item is skipped
  *
  * The items in the enumeration are obtained one at a time as
  * items from the search enumeration are requested.
