A LDAP Directory Server Model of Workflow Management Systems

The paper proposes an organization model hosted in the LDAP directory server. And it expands the scope of model utilization, gives the technical method which is capable of dealing with the heterogeneity, distribution of the organization model, and the transparency of the model to its users. Then the role-based access control (RBAC) technology has been used in the model to implement the control of resource access in the workflow management system according to the rules in the organization model. At last, this paper proposes an idea of designing an organization model information platform in workflow management systems and a prototype system. With simulation results and analysis show that the organization model has good compatibility, extendibility and high operating efficiency. Thanks to the role-based strategy, the model facilitated the management authority and suits the independence in the workflow management system for the use of organization model.
