Hi Christopher,
Thanks! I thought it might be stored in the session.
Our web app mainly supports web services. We are pretty much stateless
on the app server and don't have the notion of logging in. We don't
explicitly do anything with sessions.
Instead, we use basic authentication and the credentials are supplied
with each web service request, in the standard http headers. The clients
are not browsers, they are other applications.
If a password is changed, we need to ensure that any web service
requests sent in with old password are rejected.
I wonder if I've misunderstood the nature of the caching mentioned in
the realm how-to doc. It sounds as if the login module might be invoked
for each web service request. At any rate, it is time for me to do some
more digging and investigation.
Thanks again.

Do you mean that you want to force your users to re-login when they
change their passwords?
I've been looking through the doc and code and I've not yet found the
cache or a way to flush it.
The cached value is really associated with the session. So, if you
invalidate the session, you will destroy this cache. Since the browser
will continue to send the (old) HTTP AUTH header, Tomcat will likely
react by vetoing the re-login and respond with a WWW-Authenticate
response header. The browser will then ask the user for credentials (the
familiar pop-up username/password dialog) and the user should be
re-logged-in.
If this isn't happening smoothly, you can issue a 401 response and
include a WWW-Authenticate header manually (along with a session
invalidation) to attempt to force a re-request of the user's
credentials.
