All the hints points to Hag just giving Asura authority, and just because it's shown in the anime doesn't make it true. Since when do we use the anime as confirmation for things? Asura does not have SPSM, he was simply listed as a user just because he has a similar-looking avatar as Naruto's "Asura Kurama Mode" (which is completely ridiculous BTW). Last time I check, the databook did not list Asura as a user of SPSM. I have to disagree. I mean if it were really authority, why say power? While authority can mean power, it doesn't make sense how it is used in the context.

We do in fact use the anime for confirmation if need be as it is an official source, right behind the manga.

Also, the databook doesn't list a lot of things that we know are true, so saying that just because he wasn't listed in the databook really doesn't hold much merit.
