A very good try, Metz, and as near to a correct answer as I think anyone can get. However, we cannot do without punctuation and if you puncuate your answer correctly you will see that you have created two sentences, not one. So you haven't met the demands of the question.
Your answer, punctuated correctly, reads:
Smith, where Jones had had "had had", had had "had". "Had had" had had the examiner's approval.
The lack of puncuation renders the whole phrase meaningless and explains why ansame found none of his friends could undertand what he was talking about.
Incidentally you also got "examiners" wrong. If one examiner it is "examiner's approval". If more than one examiner it is "examiners' approval".
Don't let me see that mistake again. It was already explained to you by Foxlee two days ago.
In conclusion, the question is unanswrable in one sentence and ansame should promise never to pose it again unless he can provide an answer which meets the rules of English grammar.
