OmniAuth strategy for authenticating users using the CloudFoundry UAA server.
Set up a local ruby environment (so sudo not required):
$ rvm use 1.9.2
or
$ rbenv global 1.9.2-p180
see: https://rvm.io/ or http://rbenv.org/
Build and install the cf-uaa-lib gem located at https://github.com/cloudfoundry/cf-uaa-lib
Build the gem
$ bundle install
$ bundle exec gem build omniauth-uaa-oauth2.gemspec
Install it
$ gem install omniauth-uaa-oauth2-*.gem
See the examples folder for details on how to use it.
Warning: Unlike the omniauth-oauth2 gem, this gem does not support the oauth2 'state' security parameter.
