After installing foreman and foreman-proxy (1.0.0.rc5) on an Ubuntu 12.04 (Server, 32bit) VM, I get a red box with a 500 error when I click puppetrun. My puppet version on this setup is 2.7.17

Initially, I did not have everything setup and configured correctly when I was getting the 500. While writing this I did add the additional configuration items. I did, however still get the error after setting the additional items.

From my /etc/puppet/auth.conf:
path /run
method save
allow *

I did not have a "namespaceauth.conf" so I created one:
[puppetrunner]
allow *

1. which puppetrun
   /usr/sbin/puppetrun

I've attached a screenshot of the error as well as a (slightly redacted) copy of my puppet.conf.
