Not sure what you're saying, the aacli doesn't take ePTId as an
input. Are you suggesting to loop over all userids with the aacli?
That would work but I'm guessing will be /much/ slower than simply
finding and re-implementing the algorithm used in the generation of
the values and doing the looping outside of repeated JVM startups and
teardowns for every single subject.
