	Ahh...that makes sense.  You need to be prepared for the thing to
fail either way, but from a UI point of view, it is a good idea to just
not show something.  The way I handle that in my own tools is to have the
interface understand what groups are allowed to do which things, and have
the list of groups the user is in stored in the application.  Then I just
do something like (obviously pseudo-code):

	if(user_is_in_group("blah")) {
		showOption("options_requiring_blah");
	}
