I'm sorry but I think RTFM is not the good answer this time ;) authtimestamp is not managed by ppolicy but by the lastbind overlay. To answer the question, I think the only thing to do is check all directories to create the report. It should be not be difficult for your application developer.
Hm, good point. I guess it could benefit with the ability to forward updates as well, when configured with chaining.
