I do not believe Obama had a valid CLB from Hawaii, simply because he travelled abroad on an Indonesian passport after attaining the age of majority. If he had a valid CLB, it would have been a lot easier to obtain a US passport. Do you know how expensive and difficult it is to get an Indonesian passport when not physically resident in Indonesia, applying from the USA to Indonesia or at an Indonesian consulate? Indonesia would ask for a CLB from Indonesia. They likely got one too.There are people with two passports who use the non-US one to travel to places where anti-American feeling is strong. That may have been true of Pakistan in 1981.
If Obama used an Indonesian passport it doesn't necessarily mean he didn't have or couldn't get a US one. But do we know as a fact that he did use an Indonesian passport or is it just a surmise that he must have?
If Obama was an Indonesian citizen it's unlikely he still is, since he would have had to register with the Indonesian government periodically and hasn't. More here.

Pakistan was a US ally against the Russians in the war in Afghanistan at the time. Pakistan was a base from which the US conducted covert Ops to supply the Mahujadeen.There was no problem.
Obama did not have any other passport likley. But we can easily find that out ? Not. Ask the State Department. The assumption should be that he did not have a US passport, nor the supporting documentation for one.
