门户技术在数字化校园建设领域得到了广泛应用，统一身份认证和应用系统集成是其中的核心技术

，单点登录是实现统一身份认证的途径，提出一种利用Cookie令牌和访问控制程序来实现跨域访问控制的

单点登录方案，并使用LDAP用户数据库来完成统一的用户的登录、认证和权限管理。按照校园各种网络应

用系统的不同类型，提出了四种满足不同集成需求的系统集成方式，并在此基础上实现了基于门户的数字

校园架构。

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.
