So in support we do receive a lot of installation type calls. One thing that is discussed is the accounts needed for the installation. I decided to throw together a wiki that has the accounts needed. The goal of the article is to provide a list of accounts that is recommended to be created, and if possible prior to installation to help the install go by faster. It is a companion type article to the installation guide.
