policy.conf is missing

Hi, I want to setup FreeRadius for simple MAC based authorization. Some documents which explain Mac-Auth refer to /etc/raddb/policy.conf But I don't see that policy.conf in the rpm that I installed: freeradius.x86_64 0:1.1.3-1.6.el5 Is the above package incomplete? Or do I have to create the policy.conf? What other changes are required for Mac-auth? Thanks for any help on this. Cheers, Nagaraj
