Admin Console Quickstart links to obsolete kbase article

Chapter 3 of the Admin Console Quickstart [1] ends with the following note:

"For more information on users, how to change the default login or to add additional users, visit the Red Hat Knowledge Base: How to enable authentication on JBoss services such as rmi-http, jmx-console, and web-console?."

The linked article [2] (published in 2006) is out of date (side note: I remember Len diMaggio supplied this because at the time we did not secure the server by default before we shipped it). Now the server is secured by default, and this procedure does not need to be carried out. However, the information on how to do this might be useful if it is genericized and absorbed.

Perhaps Chapter 3 should be changed to "Configuring Access Permissions" or something like that, and fleshed out with the information from the kbase article.
