If, as it appears, Lolo Soetero took Barry and Stanley Ann Dunham to Indonesia, adopting him or claiming guardianship, enrolled him in school, and went through the correct motions of his becoming an Indonesian citizen, as paperwork evidence suggests, the US required Barry to reclaim his U.S. citizenship through his own action at the time he reached majority. If he didn't do that, and no record found suggests he did, Barry may not even be a US citizen. If documentation showing that he took an oath of citizenship long ago doesn't exist, it's possible he's an illegal alien or at minimum, no longer able to be considered a "natural-born citizen," as is required to be eligible for the presidency, even if he was able to get a US passport by showing, for example, the Hawaiian COLB Daily KOS has had on their website.
