Wow, that seemed rather uncalled for. The GM's responses seemed perfectly fine to me.
I think part of the confusion is that the game is not consistent with its use of the words "authorization" and "certification". If you see either one, pretend you're seeing both. They're used interchangeably.
The Guide linked is a good one. If it didn't work for you, what exactly were you attempting? What NPC did you go to? These are good questions.
