Subject RE: question for singlesignon for vertical cluster
Date Wed, 02 Jun 2010 22:54:24 GMT
To experts

Could someone clarify if singlesignon or clustersinglesignon on tomcat
cluster upon failover ever worked before?  
 
Tomcat 6.0.26 [64bit jdk1.6.0_20] on linux box
mod_proxy_ajp in httpd-2.2.3-43.el5.  I may upgrade it to the latest if
singlesignon works upon failover.  Otherwise, I may need to look for
another solution.

I have set up deltamanager as follows.  But I do not see any
notification upon session replication in catalina.out, but only saw log
upon startup.

I made web.xml in /examples distributable and tested session
replication, and it looks worked upon failover, but do not see any log
upon session replication.  /examples/servlets/servlet/SessionExample

I also changed conf/context.xml to make context attributes
distributable:
<Context className="org.apache.catalina.ha.context.ReplicatedContext"/>


So, is anyone able to configure singlesignon or clustersinglesignon
under tomcat cluster and make it work upon failover?

I hope this is only my configuration issue, but it looks like tomcat
cluster always asks a user to re-login upon failover no matter how it is
configured with its own singlesignon feature.

Thanks,

                   notifyListenersOnReplication="true"/>

How are you configuring the cluster in each case?

What have you tried?
