Abstract: This paper analyzes the problem of user management in computational grid, describes user classification and the limitation of user right, and devises a uniform user management system. Then the paper discusses the key technology, including user management flow, accounting, identity protocol and access to the remote cluster, which have been successfully applied to the computational grid - JobCenter-Grid.
