No : No two people have the same dna. Even identical twins who were thought to have the same dna have been found to have slight differences between the two. I attached a link to a very interesting new york times article on this subject.

Only identical twins: Identical twins have the same DNA; that is what makes them identical. Otherwise no two people will have the same DNA though we have half the same DNA as each of our parents and our siblings.
