我在使用LDAP服务器进行身份验证时，Apache Tomcat的行为方式存在问题。
当我第一次尝试登录时，一切都很好。如果我将连接空闲一段时间，然后只是注销（出于测试目的）并重新登录，它会抛出下面提到的异常，但是成功登录。为什么会这样？
请注意，如果我在未注销的情况下继续使用该应用程序，则不会发生这种情况。
这是我的服务器配置
Server version: Apache Tomcat/8.0.24
Server built: Jul 1 2015 20:19:55 UTC
Server number: 8.0.24.0
OS Name: Linux
OS Version: 2.6.18-238.el5
Architecture: amd64
JVM Version: 1.7.0_67-b01
JVM Vendor: Oracle Corporation
以下是具有异常跟踪的控制台输出。由于我退出，前两行是输出，然后当我尝试重新登录时创建异常（最终成功）
