User is logged in, has a valid authentic session, and tries to access a resource under/ portal during this session, avoiding having portal log the user out. 用户已登录,具有有效的可信会话,并尝试在此会话期间访问/portal下的资源,从而避免了门户对该用户的注销。
At least with multiple logons, the user may only be logged into one system at the time and so only one resource is compromised. 在采用多次登录方式时,用户每次只能登录进一个系统,所以只有一个资源被泄露。
Second, it allows the communication of privacy settings and manages sessions better once the person has logged out of a federated resource. 第二,它允许交换个人设置,因此在用户注销离开一项联合资源的时候,可以较好地管理Session。
