Now correctedin the page, thanks!

There was an error in the regular expression, it should be :

  ## Allow passwordless editing from own turf, pass for others.
  if ($action=='edit'
    && !preg_match("/^90\\.68\\./", $_SERVER['REMOTE_ADDR']) )    
  { $DefaultPasswords['edit'] = crypt('foobar'); }

The reg-exp is the part "/^90\\.68\\./" and, inside the quotes, it starts and 
ends with slashes which were missing, and the dots are prepended with \\.
