LDAP Authentication
I am trying to give user access through the ldap authentication but its not working. Even user put the wrong password it will authenticate to the user. please see the below script.
PHP Code:<?php
$server="XXX.XXX.XXX.XXX"; //change to ip address of ldap server
$basedn="ou=users, ou=accounts, dc=test.com, dc=com"; //change to reflect the ou and domain that your users are in.
$script=$_SERVER['SCRIPT_NAME'];
if (isset($HTTP_COOKIE_VARS['cookie']))
{ //If cookie exists, retrieve it and put it in an array for use.
$cookie=$HTTP_COOKIE_VARS['cookie'];
}
if (isset($cookie))
{
$username=$cookie['user'];
$password=($cookie['token']);
$fullname=$cookie['fullname'];
$fqdn=$cookie['fqdn'];
$dn = "cn=$username, ";
if (!($connect = ldap_connect($server)))
{
die ("Could not connect to LDAP server");
}
if (!($bind = ldap_bind($connect, "$dn" . "$basedn", $password)))
{
die ("Could not bind to $dn$basedn");
}
}
else
{
if ((isset($_POST['username'])) && (isset($_POST['password'])))
{
$username=$_POST['username'];
$password=$_POST['password'];
$filter="(&(|(!(displayname=Administrator*))(!(displayname=Admin*)))(cn=$username))";
$dn = "cn=$username, ";
if (!($connect = ldap_connect($server)))
{
die ("Could not connect to LDAP server");
}
if (!($bind = ldap_bind($connect, "$dn" . "$basedn", $password)))
{
die ("Could not bind to $dn");
}
$sr = ldap_search($connect, $basedn,"$filter");
$info = ldap_get_entries($connect, $sr);
$fullname=$info[0]["displayname"][0];
$fqdn=$info[0]["dn"];
setcookie("cookie[user]",$username);
setcookie("cookie[token]",$password);
setcookie("cookie[fullname]",$fullname);
setcookie("cookie[fqdn]", $fqdn);
}
else
