Intermediate CA Signing with Puppet

Problem statement

Many sites have a requirement to use an enterprise-wide certificate authority. They either have a "real" signing cert that chains to a public root CA or an internal root (usually air-gapped) which only signs issuing CA certificates, one per PKI application.

Puppet does not have a currently supported configuration which fits into this model. The [existing documentation][existing] describes using an "external CA" instead of Puppet's internally generated CA (which is a combined self-signed Root and issuing CA in one), but requires that the user turn off Puppet's issuance code and leaves the whole certificate generation and distribution workflow as an "exercise to the reader".

The procedure in this document describes a supportable configuration which bridges the gap between these two positions: it is possible to use Puppet's internal signing code to issue certificates from an intermediate CA cert which was externally generated and signed. There are a

(This gist is pretty old; I've written up my current approach to the Pyramid integration on this blog post, but that blog post doesn't go into the transactional management, so you may still find this useful.)

Fast and flexible unit tests with live Postgres databases and fixtures

I've created a Pyramid scaffold which integrates Alembic, a migration tool, with the standard SQLAlchemy scaffold. (It also configures the Mako template system, because I prefer Mako.)

I am also using PostgreSQL for my database. PostgreSQL supports nested transactions. This means I can setup the tables at the beginning of the test session, then start a transaction before each test happens and roll it back after the test; in turn, this means my tests operate in the same environment I expect to use in production, but they are also fast.

I based my approach on [sontek's blog post](http://sontek.net/blog/
