GridNFS is a middleware solution that extends distributed file system technology and flexible identity management techniques to meet the needs of grid-based virtual organizations. The foundation for data sharing in GridNF NFS version 4, the IETF standard for distributed file systems that is designed for security, extensibility, and high performance. The challenges of authentication and authorization in GridNFS are met with X.509 credentials, which can bridge NFSv4 and the Globus Security Infrastructure, allowing GSI identity to be used in access control lists on files exported by GridNF servers.
