Installing Plugin
=================

1) Extract archive to the plugins/ directory

2) Configure the plugin by copying the config_example.php to
config.php and modify with your Yubico Web Service API
information.  Alternatively you can copy the config_example.php
to the global config directory and rename to config_yubikey.php.

-- Configuration Options --

// yubikey_input_mode
// 1 = combined with password field
// 2 = separate input field
$yubikey_input_mode = 1;

$yubico_server_id = API_ID;
$yubico_server_key = 'API_KEY';
$yubico_server_url = 'API_URL';

Notes:  
1) API Key and URL settings are optional, the plugin will use
   the public Yubico service by default.
2) URL should follow the form http[s]://host/page?
   Ex. https://api.yubico.com/wsapi/verify?

Obtain ID and Key here:
https://api.yubico.com/yms/getapi.php

3) Go to your config directory and run conf.pl.  Choose
   option 8 and move the plugin from the "Available Plugins"
   category to the "Installed Plugins" category.  Save and exit.

  $ cd config/
  $ ./conf.pl
