authcheck vs. groupcheck with FreeRadius 2.1.1

Hello, we're migrated from Freeradius 0.9 to 2.1. We are using the freeradius with a failover MySQL Configuration. Since the migration we have customers which get in trouble, because we configured "Simultaneuos Use" Check Items on the user (e.g. Value 4) and on the corresponding group (e.g. Value 2). At the old Radius version the value was taken from the User and the Group attribute was ignored. Now the user can't authenticate 4 times, because the server checks the group value. How can I change this behaviour? If you need configuration fragments, please tell and I will supply them. Thanks a lot and best regards Michael Schramm
