Security documentation does not provide adequate information to integrate additional domains for authentication

The Administration Guide mentions modifying/adding domains that Teiid use for authentication, but never mentions how to accomplish it. There should be information to edit the 'teiid-jboss-beans.xml' file to add/edit domains in the "securityDomains" property in order for users to easily modify authentication according to their security needs.
