America's Ultimate Long Distance Riders (AULDR) is not in any way affiliated with the Iron Butt Association. As one article on the group wrote:
"The members of the [AULDR] group considered riding to be more of a lifestyle, as opposed to a competition. The competitive side of the group was to keep it fun and interesting, as the more points you accumulated when riding, the higher position you obtain on the board. As an incentive, and to pay homage to the
Iron Butt Association (IBA), he thought it would be nice to provide an extra credit for having rides certified [by the IBA]."
And that's about the extent of any connection. There is no such thing as "Iron Butt points" as far as the Iron Butt Association is concerned. It is purely a construct of this other riders group.
