Application of Organization Model Based on LDAP Directory Server to Workflow Management System

As an important part of workflow management system, the organization model is being challenged by some difficulties such as cross-region, heterogeneous systems and so on. Firstly, this article proposes an organization model hosted in the LDAP directory server. This scheme 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 this article to implement the control of resource access in the workflow management system according to the rules in the organization model. At the end, this article proposes an idea of designing an organization model information platform in workflow management systems and a prototype system. After experiments and analysis, we proved this 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 work flow management system for the use of organization model.
