All,

For the record, this is not in fact the case. I've used some SQL-fu to 
"fix" the problem but I'm still seeing a (very) few changing records 
where the WLC reports "Acct-Authentic = RADIUS" for a username which 
most definitely is *not* valid.

Sigh; anyway, I'll be opening a bug with Cisco about this.
