NSBD is one of the most important information management systems.Among them the user management system is the most important part,which made a well deployment for all users and resource to make sure that every user was reasonable privilege in resources.NSBD information system contains large amount of subsystem resources.Each subsystem not only contains their own system-users,but also some other construction management users.So it is a tough problem to reasonably allocate the system resource and the corresponding privilege to each user.Furthermore,because of the large numbers and complicated structure of system resources,a quick response for each user's request is also a very important fact.This paper issued a solution which can perfectly resolve these problems and meet the needs of users capably.It is a user management mechanism that is based on LDAP with two-stage privilege control,respectively designed management mechanisms for the portal and all subsystem to ensure the portal's controlling subsystem,and subsystems' controlling on the detailed resources.Furthermore,considering the data concurrency,we presented a brand data-storing style, LDAP and Database,the data which need frequently modifying will be stored in Oracle Database,but some others will be stored in the server of LDAP,which is well-known for its quick response to query.
