-- http-default-accounts-fingerprints.lua
-- This file contains fingerprint data for http-default-accounts.nse
--
-- STRUCTURE:
-- * <code>name</code> - Descriptive name
-- * <code>category</code> - Category
-- * <code>login_combos</code>
---- * <code>username</code> - Default username
---- * <code>password</code> - Default password
-- * <code>paths</code> - Paths table containing the possible location of the target
-- * <code>target_check</code> - Validation function of the target (optional)
-- * <code>login_check</code> - Login function of the target
--
-- TODO: Update the functionality of <code>target_check</code> to differentiate 
--       between valid HTTP/200 and a custom error page.
