Hi All,

The current JAAS based authentication in Tomcat (6.0.2) , has no means of
manipulating the associated credentials. This prevents an application from
specifying more complex security policies. For example, timing out the roles
independent of the session timeout.

A very simple fix would be to make the subject object accessible from the
session object. Once could then, for example, use a valve to enforce custom
security policies.

Though not part of servlet specification (from what I can tell), are there
any strong reasons for not supporting this feature.

Thanks much,

Shivaraj
