问题
I have used chef version 11 without any issues. Now that I hear the new version 12 is out, I wanted to use the same. So, on a fresh aws instance I downloaded the chef-server-core-12.0.0-1 installed it right away. Now going forward, I used the command,
chef-server-ctl reconfigure
to start all the services as mentioned in the official document. Now this step should also create a new admin, a validator that will be used in knife.rb. This was taken care of in the chef version 11. Now I am unable to generate the admin.pem and chef-validator.pem without which I cannot setup a new workstation.

I can't do more than give you the documentation link:
http://docs.chef.io/install_server.html#standalone
Read carefully and you'll see you have to create the first organization and first admin for this organization (steps 5 and 6).
Chef 12 is a major version change, which state there's probably breaking changes...
A lot of communication have been made on chef.io blog, take time to read about it before giving it a try, you'll save time.

admin.pem is nothing but the clients pem file.
whenever you bootstrap the node using knife command. client.pem or admin.pem or node.pem file is automatically generated under /etc/chef/client.pem
