Authenticated vs anonymous OD binding

Could someone help me understand the functional difference between binding to OD with authentication or not? I'm configuring a simple golden triangle, and my 10.5.8 server is only going to dish out MCX to the clients; no file, web, print or network services. Considering what I'm using the server for, is there any compelling reason to use authenticated binding? (I do like that the computer account gets created in OD, v.s. not when binding blind) thanks, Darrin
