Highly computational resource sharing environments like grids pose major security issues. Secure interoperability has been a growing concern for such multi domain computing systems. Collaboration in such a diverse environment requires integration of all local policies to compose a global access control policy for controlling information and resource. Access control in such an environment is still an open problem. The much standardized Role Based Access Control (RBAC) is yet to be fully utilized in a multi domain grid environment like the grids.
