Is there a technote on this? Is this an Apple convention or do other nix's share the underscore uname duplication? Maybe there is a non Apple doc on this behavior?

All my testing and searching has always shown the two username forms to be interchangeable. (As long as the alias exists in the record, which I think happens automatically.)

I have always wondered the official guidelines on the username format as well as official documentation on the uses of the underscore in a username or group.
