JaRBAC is a Logic engine/library written in java to enable RBAC in an access controller. It was a class requirement but I started to like access control mechanism and followed the trail to Distributed Access Control mechanisms, such as PolicyMaker, Rt0, Ketnote, SPKI/SDSI.\
Jarbac strictly follows the RBAC rules that needs to be defined in the rule file. Being moduler, it can be easily ported to any access controller that wants use RBAC.
