Exec-Program-Wait and FreeRadius 2.1.1

Hello, we're about to migrate from Freeradius 0.9 to 2.1. During this we're noticed, that the Atribute "Exec-Progam-Wait" and "Exec-Program" are deprecated. We used this feature to start a script (which generates special Cisco AV-Pairs). Our Freeradius backend is a mysql database. Now my Problem is that the attributes doesn't work. So we tried with the exec module. Thie works fine, but we want to execute different scripts depending on the the group the user is inserted and I want to manage this via Databse like it was in version 0.9. Can you give me a clue how to deal with, because didn't find anything about this in the documentation. Thanks a lot and best regards Michael Schramm
