I don't like using preauth, because I loose all the buolt in permission
'authentication_scheme' (admin etc, great stuff),
and when I install a package that uses phplib I'm stuck

Here is the code I finally sorted out

Index page:
.....

<?
  page_open(array("sess" => "Example_Session",
  "auth" => "Example_Default_Auth", // default authentication, no login
required
  "perm" => "Example_Perm", "user" => "Example_User"));
$sess->register("dologin"); //say to welcome we want to login
$dologin=true;
?>
<FORM action="welcome.php" method=post>
Login
<INPUT name=username size=10 value="">
Password
<INPUT name=password type=password size=10 value="">
<INPUT type=submit value="login"><BR>
</FORM>
<?
page_close();
?>
             

....
welcome page:

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

if (isset($dologin) && $auth->auth["uid"]=="nobody") // have we been
asked a login?
    {
    if ($auth->auth_validatelogin()) // were the provided $username and
$password correct?
                    // watch! some versions of local.inc return true
also for nobody
        {
        $sess->unregister("dologin"); // you're OK, next time pass
through
        page_close();
        header("Location: ". $sess->url($PHP_SELF)); // come back here
now
        }
    else // provided $username and $password are not OK
        {
        $auth->auth_loginform(); // enter the normal authentication
(show a register form
        exit;
        }
    }
else // dologin not set
    {
    $auth->mode="reg"; // show a register form
    $auth->login_if("doit"); // enter the normal authentication (show a
register form
    }
?>
WELCOME USER
<?
page_close();
?>
