Description John Mazzitelli 2009-04-01 16:15:00 EDT
registering an agent with a loopback address (localhost or 127.0.0.1) is only for testing/demoing the agent. you should never do this in production because that agent will only ever be able to interact with a server on the same box (e.g. agent cannot participate in HA).

Log warnings in both agent and server log files when an agent registers with a loopback.  The functionality should not change - the agent can still register and work as before, this is just to log a message to inform people when this happens in case there was a problem with DNS mappings that a user isn't aware of (or perhaps they entered the wrong values in the setup prompts).
