Simple and fast authentication module when you want to authenticate your users againt Active Directory through LDAP. The script will also store the username, Display Name, and fully qualified DN ie; DN=user,ou=users,ou=account,dc=domain,dc=com in a cookie. You could also store any other attribute of the user in the cookie as well (email address, office phone, etc...) Note: you will need to change the server, basedn and filter variables for your environment. Just place an include "auth.in"; at the top of every file that you want protected. <? $server="XXX.XXX.XXX.XXX"; //change to ip address of ldap server $basedn="ou=users, ou=accounts, dc=domain, 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))"; //define an appropriate ldap search filter to find your users, and filter out accounts such as administrator(administrator should be renamed anyway!). $dn = "cn=$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 { ?> <html> <head> <title>Portal Login</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <meta http-equiv="expires" content="0"> <meta http-equiv="pragma" content="no-cache"> </head> <SCRIPT LANGUAGE="JavaScript"> <!-- document.onmousedown=click; function click() { if (event.button==2) {alert('Right-clicking has been disabled by the administrator.');} } //--> </SCRIPT> <div align="center"> <form method="post" action="<? echo $script; ?>"> <div align="center"> <table width="210" border="0" cellspacing="0" cellpadding="0"> <tr> <td align="center"> <fieldset> <Legend><font face="Verdana,Tahoma,Arial,sans-serif" size="1" color="gray">Enter Credentials</font></Legend> <table border="0" cellspacing="3" cellpadding="0"> <tr> <td align="right" valign="middle"><b><font face="Verdana,Tahoma,Arial,sans- serif" size="1" color="gray">Username:</font></td> <td align="center" valign="middle"> <input class="clear" type="text" size="15" name="username"> </td> </tr> <tr> <td align="right" valign="middle"><b><font face="Verdana,Tahoma,Arial,sans- serif" size="1" color="gray">Password:</font></td> <td align="center" valign="middle"> <input class="pass" type="password" size="15" name="password"> </td> </tr> </table> <input type=image src="images/login.gif" alt="Login" name="image"> <br> </div> </td> </tr> </fieldset> </table> <br> <table width="640"><tr><td align="center"> <font face="Verdana,Tahoma,Arial,sans-serif" size="1" color="silver">This System is for the use of authorized users only.
