Freeradius & Sybase

Hi All, I'm unsing freeRadius 2.1.3 over SUSE Linux. I'm trying to set SQL accounting with a sybase DB, but unsuccesfully. Anyone can tell me what sybase pluging I have to use? Thnks in advance, Francesco Toro. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
