I have written one new module rlm_xyz which i am using to handle both authentication and accounting requests from NAS. When authentication fails, I am replying with Access-Reject message but when Accounting request fails, I am not sending any reply to the NAS. Since NAS doesn't get reply, it is resending the same accounting request to the server.

That's how RADIUS works.

My problem is i want the free radius stack to handle the duplicate requests instead of passing the request to my rlm_xyz module. Please lemme know if any configuration details are required.

FreeRADIUS doesn't work like that. It is *your* responsibility to track these duplicate requests. That's why FreeRADIUS has modules like "SQL". They track these duplicate requests. FreeRADIUS does not include a long-term database to track accounting packets. It will *never* have such an internal database. That's what SQL is for. The SQL server does database things, FreeRADIUS does RADIUS things. Alan DeKok.
