autologon

Performs an auto login from an external page

• Shipped by Roundcube
• Plugin name: autologon

You have to modify the default Thomas Bruederli's sample plugin like this (eventually change to $_GET):

<?php

/**
 * Sample plugin to try out some hooks.
 * This performs an automatic login if accessed from localhost
 *
 * @license GNU GPLv3+
 * @author Thomas Bruederli
 */
class autologon extends rcube_plugin
{ 
  public $task = 'login';

  function init()
  {
    $this->add_hook('startup', array($this, 'startup'));
    $this->add_hook('authenticate', array($this, 'authenticate'));
  }

  function startup($args)
  {
    $rcmail = rcmail::get_instance();

    // change action to login
    if (empty($_SESSION['user_id']) && !empty($_POST['_autologin']) && $this->is_localhost())
      $args['action'] = 'login';

    return $args;
  }

  function authenticate($args)
  {
    if (!empty($_POST['_autologin']) && $this->is_localhost()) {
      $args['user'] = $_POST['_user'];
      $args['pass'] = $_POST['_pass'];
      $args['host'] = '[localhost | mail-server-IP]';
      $args['cookiecheck'] = false;
      $args['valid'] = true;
    }

    return $args;
  }

  function is_localhost()
  {
    return true;
//    return $_SERVER['REMOTE_ADDR'] == '::1' || $_SERVER['REMOTE_ADDR'] == '127.0.0.1';
  }

}

Use a form like this one in your CMS page:

<form name="form" action="https://your.webmail.url/" method="post">
<input type="hidden" name="_action" value="login" />
<input type="hidden" name="_task" value="login" />
<input type="hidden" name="_autologin" value="1" />

<table>
<tr>
    <td>Utente</td>
    <td><input name="_user" id="rcmloginuser" autocomplete="off" value="" type="text" /></td>
</tr>
<tr>
    <td>Password</td>
    <td><input name="_pass" id="rcmloginpwd" autocomplete="off" type="password" /></td>
</tr>
<tr>
    <td colspan="2"><input type="submit" value="Login" /></td>
</tr>
</table>

</form>
