Design Of Digital Tourist Management Based On LDAP Authentication

User management always is the network information system key. The management to the user who enters the enterprise information system is whether effective involves the enterprise information safety factor directly. Therefore, these management has been regarded extraordinarily.Many technologies can be use to limit the accessing user , Authentication and the Access Control are two essential technologies.Single sign-on (SSO) is a very important way. Through single distinguish and authentication movement, can allow the user visit all the computers and application systems without inputting more system password. SSO reduces the artificial mistake and system major failure. The thesis discusses the method and realization about SSO.The research of this thesis is: Development of unified management to the users in enterprise information management system ,and Role-Based Access Control (RBAC),Single Sign On (SSO).The mainly involved development and research are as follows:1. Narrates the status management and authentication technology as well as the present situation of the authority management and the access control technology development.2. Studies Role-Based Access Control in a deepgoing way. on the base of it, extended RBAC and brought out the model of Rule-driven RBAC,giving a realization of the RBAC in the Enterprise Information Management System.3. Take the development of unified management to the users in the enterprise information management system as an example, explaned the question which involves based on the RBAC.4. Based on the study of the authentication and SSO technology, the thesis gives the model of the SSO that brought about by unified management to the users and Kerberos in the Travel Information Management System.5. Shows the realization of the SSO Access Control in the Enterprise Information Management System.
