how to configure authorization using Active Directory + SQL

Hello, I am trying to configure a RADIUS authentication server by linking FreeRADIUS and Active Directory. Authenticating in Active Directory using the mschap module was successful. However, I do not know how to set up authorization, so I ask. after merging reply items in the authorize {} section i want to authenticate using Active Directory(mschap), can I merge reply items using the sql module? Or, if there is another way, please help. I'm using EAP-PEAP(MSCHAPV2). thank you for your help.
