rack-cas_client¶ ↑

• github.com/bhenderson/rack-cas_client

DESCRIPTION:¶ ↑

A Rack Middleware component to authenticate against a CAS server.

I (shamefully) forgot to attribute this to github.com/garnieretienne/rubycas-client-sinatra. I had reached out to garnieretienne and he was no longer interested in his project. There is also rack-cas-client gem but that was too rails focused for me.

FEATURES/PROBLEMS:¶ ↑

• Tries to be a simple authentication mechanism and leaves it up to the app chain to determine endpoints that should be auth’d.

• Does not depend on Sinatra or Rails.

• Does use ‘rack.session’ so anything that uses that will work.

• Passes options hash to CASClient::Client (see docs for exceptions)

SYNOPSIS:¶ ↑

# config.ru

require 'rack/cas_client'

use Rack::Session::Cookie

map '/login' do
  run Rack::CASClient.new nil, :cas_base_url => 'https://example/cas'
end

class MyApp < Struct.new(:app)
  def call(env)
    request = Rack::Request.new env
    response = Rack::Response.new

    user = request.session[:cas_user]
    unless user and not user.empty?
      query = URI.encode_www_form url: request.url
      response.redirect "/login?#{query}"
      return response.finish
    end

    response.write "hi #{user.inspect}"
    response.finish
  end
end

run MyApp.new
