HTTP Authentication problem?

[shakeelstha]

<?php

ob_start();

session_start();

 

$auth_user="manager";

$auth_pwd="manager";

 

if($_SERVER['PHP_AUTH_USER']==$auth_user && $_SERVER['PHP_AUTH_PW']==$auth_pwd && $_SESSION['authorized']==1)

{

include_once("session.php");

open_session_admin($auth_user);

  header("Location: resadmin.php");

//echo "you are logged in......</ br>";

}

else

{

$_SESSION['authorized']=1;

    authenticate();

}

 

function authenticate()

{

    header('WWW-Authenticate: Basic realm="Enter Your Login detail to access the page"');

    header('HTTP/1.0 401 Unauthorized');

    echo "You must enter a valid login ID and password to access this resource\n";

    exit;

}

?>

 

 

 

This code runs well in localhost in windows platform. But after uploading it to linux server, it doesn't work. What is the problem?

How doesn't it work?

Like daniel0 said, any error messages, anything else for us to go on, there may be dozens of possible problems, possibly even out of our scope.
