Setting up JBoss EAP in Domain Mode with Remote Host Controllers ?

Issue

• We want to configure domain mode with host controllers will be running on a remote box.
• Do you have any suggestions for debugging connections between host and domain controllers?
• Is there a way to use single user for multiple host-slave controllers?
• Is there a way to use username attribute that can be connected to the domain controller and shared amongst all slave nodes?
• Is there any documentation with detailed steps to set-up Remote Host Controllers ?
• Host controller could not connect / attach / find remote domain controller.
