Hi all I have a web application running on Tomcat 7.0.14 and I'm using LDAP for user authentication. The problem is that when a user logs in after an inactive period the following warning comes out. The inactive period doesn't have to be long, as only few minutes is enough. However, the user is able to log in despite of the warning. From the users' point of view the application behaves normally, but Tomcat log reveals the warning below. CODE --> javaJun 6, 2012 9:41:19 AM org.apache.catalina.realm.JNDIRealm authenticate
