Abstract:

Portal technology has been widely applied in the digital campus construction,and

unified authentication and application system integration is one of the core technologies.

Single signon is a method to achieve a unified portal authentication. An approach is

proposed which uses cookie tokens,access permissions and control procedures to achieve cross

domain access,and uses the LDAP database to complete the user's login,authentication and

rights management. According to different types of network applications in the campus,four

kinds of integration methods to meet different needs are also introduced.
