how can i prevent JAAS to buffer users?

Hi all,

For security, we are using JAAS (in JBoss). The problem is whenever the user enters the application and logs out. Later then user gets deleted and its getting deleted in database. But if i login using"deleted user", instead of showing invalid login details, it is taking me to application and then causing the error(as the user doesn't exist in database). if i restart the server, then server is showing invalid login details page(working fine). I can say that user getting buffered in server(may be by JAAS) whenever user logs in. how can i prevent the server(or JAAS) to buffer those users.
