Some feedback I've heard from new Ipsilon admin users is that they are not sure what each plug-in page is meant to do. Some helpful basic description paragraphs could help here. For example, something similar to:

"Login plugins are responsible for authenticating users to Ipsilon. You can enable different login plugins to allow users to authenticate using different authentication methods."

In addition, some tool-tips that pop up when you hover over UI elements might be helpful to explain what text-fields or buttons do.
