There was one reference I read prior to the 2008 election that specifically said 0bama is in no way connected with the Dunhams. The article also discussed the man who was sent to Indonesia to grab records earlier in the 2000s.
You cannot find that article now.
Lt Q. Harris must have known, though.
The article you are perhaps referring to is:

An American Expat in Southeast Asia blog is written by FR’s own expatguy.
The blog is interesting, particularly the articles written in 2007 and 2008. This man knows a lot about Obama.
