无法使Spring 3 Session Concurency Control工作

Question

使用Spring Security 3.1.0,我似乎无法使并发会话控制功能起作用.当我使用IE和FireFox(使用我的本地工作站)同时登录我的系统时,我在会话注册表中看到我的用户原则两次.我期待并发会话控制将我退出或抛出异常或做一些事情表明我多次登录该网站并且不允许这样做.

对于它的价值,即使指定我的站点使用自定义登录表单,我也无法使用HTTP名称空间元素的自动配置来使用并发控制.我想知道这可能是因为我的身份验证是通过LDAP提供的吗？

这是我的安全配置.

我是否遗漏了一些属性,如果用户记录多于1个会话,应该告诉并发控制策略barf？我知道同一个用户正在记录多个会话 - 因为我在会话注册表中看到了重复的原则.

任何/所有回复都非常感谢!提前致谢!

Answer 1

SessionRegistry使用equals()/ hashCode()中UserDetails找到相同的用户的会议.如果你有自定义UserDetails,也许它没有实现.
