+ * - it should be impossible to "see" the length of the stored password
+ * - a changed password must be persisted
+ * - forms might be subject to multiple submissions in case other fields fail.
+ *   If the user changed the password during the first submission attempt, the
+ *   new string should not be lost.
+ * - all this must happen within the bounds of ZF1 form elements and related
