Auth-Type and Group precedence

Hey guys, Setting an Auth-Type := Accept to a user while also associating the same user to a group with Auth-Type := Reject results in a successful login of the user due to the Auth-Type := Accept in radcheck table taking precedence. Is it possible to give a higher priority to the group association? System is a FreeRADIUS 1.1.7 install with a mysql database backend. Regards, Liran.
