Session issues on remote host with user authentification

permalink · #1 (**permalink**) 08-07-2008, 11:03 AM

I build an application with Dreamweaver CS3 containing a private space
where users have to login.

It runs perfectly on my local host (using PHP 4.3.10) : users can
login with any trouble ; but user authentification doesn't work on the
remote host (using PHP 4.4.0).

I use the code generated by Dreamweaver for user athentification, no
change, no specific dev.

I have the intuition that there is a problem with the storage of the
session variables on the server. Here is my local host parameters :
session.save_path : C:\PROGRA~1\EASYPH~1\\tmp\
session.serialize_handler : php
session.use_cookies : On
session.use_only_cookies : Off
session.use_trans_sid : Off

Here is my remote host parameters :
session.save_path : /tmp
session.serialize_handler : php
session.use_cookies : On
session.use_only_cookies : Off
session.use_trans_sid : On

Do you have an idea how i can solve this problem ? I noticed that on
my local host the session.save_path is the physical directory and on
my remote host the session.save_path is a virtual directory...

I did some tests on my servers to discover the cause of this issue.

I put the regular login page on the both (local and remote) servers
but i changed the $MM_redirectLoginSuccess page in both with the
following page :

<?php
if (!isset($_SESSION)) {
session_start();
}
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://
www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>New Page</title>
</head>

<body>
<h1>Coucou ! Ca marche !</h1>
<p><? echo $_SESSION['MM_Username']; ?></p>
<p><? echo $_SESSION['MM_UserGroup']; ?></p>
</body>
</html>

On my local server the $_SESSION['MM_UserGroup'] is correctly
displayed on the redirect page, on my remote server
$_SESSION['MM_UserGroup'] is empty !!!

Do you have any idea ? I would be very gratefull...
