Get an instance of OpenAM up and running using Vagrant and Puppet.
git clone https://github.com/phinze/openam-vagrant.git && cd openam-vagrant
That's it! The VM will be created and Puppet will download and configure OpenAM for you.
OpenAM will come up on port 80 of the VM, which should be available at: http://192.168.33.10
Currently I'm just having this set up a default identity provider, but soon I'll fill in more details about the Puppet types provided and how to configure OpenAM with them. For now you can poke around the source; feel free to open an issue with a question if you have one.
