[add LDAP alternative to login function]

Hello there,

 

I have this as login in function for an application.

 

function login($username, $password) 

    {

        $db =& $this->db;

 

        Kit::ClassLoader('userdata');

 

        if (Config::Version('DBVersion') < 62) {

 

            // We can't do CSPRNG because the field doesn't exist, so we need to do standard user login

            // This can ONLY happen during an upgrade.

            $dbh = PDOConnect::init();

            $sth = $dbh->prepare('SELECT UserID, UserName, UserPassword, UserTypeID FROM `user` WHERE UserName = :userName');

            $sth->execute(array('userName' => $username));

 

            $rows = $sth->fetchAll();

 

            if (count($rows) != 1) {

                setMessage(__('Username or Password incorrect'));

                return false;

            }

 

            $userInfo = $rows[0];

 

            // Check the password using a MD5

            if ($userInfo['UserPassword'] != md5($password)) {

                setMessage(__('Username or Password incorrect'));

                return false;

            }

 

        }

        else {

            // Get the SALT for this username

            if (!$userInfo = $db->GetSingleRow(sprintf("SELECT UserID, UserName, UserPassword, UserTypeID, CSPRNG FROM `user` WHERE UserName = '%s'", $db->escape_string($username)))) {

                setMessage(__('Username or Password incorrect'));

                return false;

            }

 

            // User Data Object to check the password

            $userData = new Userdata($db);

 

            // Is SALT empty

            if ($userInfo['CSPRNG'] == 0) {

 

                // Check the password using a MD5

                if ($userInfo['UserPassword'] != md5($password)) {

                    setMessage(__('Username or Password incorrect'));

                    return false;

                }

 

                // Now that we are validated, generate a new SALT and set the users password.

                $userData->ChangePassword(Kit::ValidateParam($userInfo['UserID'], _INT), null, $password, $password, true /* Force Change */);

            } else {

 

                // Check the users password using the random SALTED password

                if ($userData->validate_password($password, $userInfo['UserPassword']) === false) {

                    setMessage(__('Username or Password incorrect'));

                    return false;

                }

            }

        }

        

        // there is a result so we store the userID in the session variable

        $_SESSION['userid'] = Kit::ValidateParam($userInfo['UserID'], _INT);

        $_SESSION['username'] = Kit::ValidateParam($userInfo['UserName'], _USERNAME);

        $_SESSION['usertype'] = Kit::ValidateParam($userInfo['UserTypeID'], _INT);

 

        // Set the User Object

        $this->usertypeid = $_SESSION['usertype'];

        $this->userid = $_SESSION['userid'];

 

        // update the db

        // write out to the db that the logged in user has accessed the page

        $SQL = sprintf("UPDATE user SET lastaccessed = '" . date("Y-m-d H:i:s") . "', loggedin = 1 WHERE userid = %d", $_SESSION['userid']);

        

        $db->query($SQL) or trigger_error(__('Can not write last accessed info.'), E_USER_ERROR);

 

        // Switch Session ID's

        global $session;

        $session->setIsExpired(0);

        $session->RegenerateSessionID(session_id());

 

        return true;

    }

 

i am trying to squeeze in an alternative authentication for users on ldap as such if local authentication fails

 

  // alternativelly validate against  Tivoli Directory server

$ldap_host = "www.zflexldap.com:389";

$password = "password";

    // Tivoli  Directory DN

    $ldap_dn = "ou=users,ou=guests,dc=zflexsoftware,dc=com";

    // connect to active directory

    $ldap = ldap_connect($ldap_host)

        or die("Couldn't connect to LDAP Server");

   //username specified on post form is from TDS server

   // $dn = "uid=".$username.",";

    $dn = "uid=guest1,ou=users,ou=guests,dc=zflexsoftware,dc=com";

ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);

    // verify user and password

    if($bind = @ldap_bind($ldap, $dn, $password)) 

 

all attempts thou has been breaking the application.

 

thanks
