Subject How to force each session to authenticate
Date Tue, 05 Sep 2006 13:19:00 GMT
I am using jboss and I trying to change the default caching behavior for 
username/passwords. I would like to force each session to reauthenticate.

The first time the user logs in, the my login module is called and it 
goes through login & commit as expected. The user's credentials are 
cached. The second time the user logs in (the user has not logged out 
from the first login but logs in using a different browser of a 
different machine). The cached credentials are used. I believe that a 
subclass of org.apache.catalina.realm.RealmBase is where the credentials 
are stored but I can't determine which subclass is used and how or where 
to specify a custom class that overrides the RealmBase.authenticate 
method. I am using form based login and see that 
org.apache.catalina.authenticator.FormAuthenticator is called. Where are 
all the default classes that are instantiated specified?

The server.xml snippet specifying the Realm is:
   <!-- Use a custom version of StandardService that allows the
  connectors to be started independent of the normal lifecycle
  start to allow web apps to be deployed before starting the
   <Service className="org.jboss.web.tomcat.tc5.StandardService" 
name="jboss.web" debug="99">
       <!-- A HTTP/1.1 Connector on port 8080 -->
       <Connector acceptCount="100" address="${jboss.bind.address}"
           connectionTimeout="20000" disableUploadTimeout="true"
           enableLookups="false" maxSpareThreads="75" maxThreads="150"
           minSpareThreads="25" port="8080" redirectPort="8443"/>
       <!-- A AJP 1.3 Connector on port 8009 -->

           keystorePass="38828tavve57" maxSpareThreads="15"
           maxThreads="100" minSpareThreads="5" port="8443"
           scheme="https" secure="true" sslProtocol="TLS"/>
