17.6.3. Configure a mod_cluster Worker Node

4. Configure authentication for each slave host.

Each slave server needs a username and password created in the domain controller’s or standalone master’s ManagementRealm.

Why? What?

5. How does it relate to mod_cluster?

Please, move and/or remove references to creating Domain or securing slave hosts in Management Domain. mod_cluster worker configuration has nothing whatsoever in common with any user accounts, Domain management, hosts, slaves, controllers etc. It's an entirely different topic. The current text is vastly confusing to the point of actually convincing the reader that for one to use JBoss EAP as a mod_cluster worker, it is necessary to start with Domain configuration and user accounts. It ain't. It's perfectly O.K., to spin up two standalone-ha instances and let them connect to the mod_cluster proxy; no need for any Domain settings or user accounts.

WDYT?
