Looking into it a bit further, I found that the hard-coded password
form comes only when PmWiki's forms are disabled. Then, the code below
will handle both cases:

function SetAuthMessage($pagename) {
  global $MessagesFmt, $action;
  $actionText = array(
    'attr' => 'administer',
    'upload' => 'upload files related to',
  );
  $handle = @$actionText[$action];
  if(!$handle) $handle = $action;
  $MessagesFmt[] = "<p><i>You need to authenticate yourself to $handle
this page.</i></p>";
}

if(IsEnabled($EnableForms,1)) {
  $AuthPromptFmt = array(&$PageStartFmt,
    'function:SetAuthMessage',
    'page:{$SiteGroup}.AuthForm',
    "<script language='javascript' type='text/javascript'><!--
      try { document.authform.authid.focus(); }
      catch(e) { document.authform.authpw.focus(); } //--></script>",
    &$PageEndFmt);
}
else {
  $pagename = ResolvePageName($pagename);
  SetAuthMessage($pagename);
  $AuthPromptFmt = array(&$PageStartFmt,
    "<p><b>$[Password required]</b></p>"
    . implode('', $MessagesFmt)
    . "<form name='authform' action='{$_SERVER['REQUEST_URI']}' method='post'>
       $[Password]: <input tabindex='1' type='password' name='authpw'
       value='' />
       <input type='submit' value='OK' />\$PostVars</form>
       <script language='javascript' type='text/javascript'><!--
       document.authform.authpw.focus() //--></script></form>",
    &$PageEndFmt);
}
