OmniAuth::OpenID

Provides strategies for authenticating to providers using the OpenID standard.

Installation

gem install omniauth-openid

Stand-Alone Example

Use the strategy as a middleware in your application:

require 'omniauth-openid'
require 'openid/store/filesystem'

use Rack::Session::Cookie
use OmniAuth::Strategies::OpenID, :store => OpenID::Store::Filesystem.new('/tmp')

Then simply direct users to /auth/open_id to prompt them for their OpenID identifier. You may also pre-set the identifier by passing an identifier parameter to the URL (Example: /auth/open_id?openid_url=yahoo.com).

A list of all OpenID stores is available at http://github.com/openid/ruby-openid/tree/master/lib/openid/store/

OmniAuth Builder

If OpenID is one of several authentication strategies, use the OmniAuth Builder:

require 'omniauth-openid'
require 'openid/store/filesystem'

use OmniAuth::Builder do
  provider :open_id, :store => OpenID::Store::Filesystem.new('/tmp')
end

Configured Identifiers

You may pre-configure an OpenID identifier. For example, to use Google's main OpenID endpoint:

use OmniAuth::Builder do
  provider :open_id, :name => 'google', :identifier => 'https://www.google.com/accounts/o8/id'
end

Note the use of nil, which will trigger ruby-openid's default Memory Store.
