What do you mean by 'it protects the content further down the page'?
Does only a part of the page show up? or the loginform.ihtml page?

There are two cases: 
a) you want to show a login form in a common page that, when submitted,
drives to another page
b) you want to show a login form in a common page that, when submitted,
comes back to that same page


for case a) you don't need any feature in the containing page, not even
session. You need at least session and auth in the 'after login' page 
for case b) you need session+default auth in the containing page, (which
is also the after login page)

case a) is a lot simpler. you set a form in pagea with action=pageb.php
and the two input fields username and password, in pageb.php you do:

    <?
      page_open(array("sess" => "Example_Session",
      "auth" => "Example_Auth",   // you need this
      "perm" => "Example_Perm", "user" => "Example_User"));

    if (!$auth->auth["uid"]=$auth->auth_validatelogin())
            {
            $auth->login_if("doit");
            }
    ?>
    WELCOME USER
    <?
    page_close();


case b) is more compliacted. 
as pagea.php, in this case acts as both the sending and receiving page,
you need default auth here. and redirect to itself. I'll like this
popular hack to be canonicized somehow. as the back button and
cancel-login button hacks. 
get some ideas from
http://www.geocrawler.com/archives/3/195/2001/7/300/6167151/
but set the action to $PHP_SELF and echo the form instead of calling
$auth->auth_loginform

I can't tell you more about case b) , see if case a) fits for you first.
