mysql accounting

I have a quick question on the mysql accounting. I am working on my own interface for managing the freeradius+mysql setup. Everything is working great, I can view all my users, see who's connected, add new users, manage static vs. dynamic IP's, etc..The problem is it doesnt seem to log authentication failures into the radacct table. It logs all the successes just fine, but it would be very beneficial to have it log the failures too. I have the sql module turned on in the accounting section of the config and have uncommented all of the accounting queries. Any help appreciated.
