Apologies Joseph, you are correct.  I just re-checked the ASMIDF manuals and 
they do not directly say that it supports debugging authorized code.  The Fine 
Manuals actually don’t say one way or another whether authorized debugging is 
supported, but since it is not specifically documented as possible I would 
presume that it is not.

I suppose you could try making ASMIDF itself authorized in an APF library so 
you could try debugging authorized code, but I suspect that exercise would end 
up causing more problems than it may be worth.

Last time I visited IDF didn’t debug code in supervisor state
