Are you sure that both Tomcat clustering and CAS clustering are
configured correctly?  By using Tomcat 5.5, I assume that you are using
multicasting for both Tomcat and CAS; only Tomcat 6.0 supports unicast
discovery via static members.

I'm not really expert about tomcat , but I can say that it's clustering
works because I can see that each established connection generates a
sessionID wich is visible by both the servers using a test jsp. 

[Andrew R Feller] 

	Try changing the logging level to debug for the
org.apache.catalina.cluster package to confirm that Tomcat clustering
works.  As for CAS, I think you should be able to log at the
org.jasig.cas.ticket.registry package to monitor the JBoss Cache ticket
registry.

jboss cache 2.0 

tomcat 5.5 

cas 3.0.7 

I'm sorry but as I said before I'm not really expert about tomcat. Could
you explain how to do this to me in a step-by-step way? ;P 

Furthermore, we're using Jboss Cache 1.4.1SP4, Tomcat 5.5 and CAS 3.0.7
with JDK 1.6. Should these versions be compatble with each other?

	Hope that helps,

	Hi all,

	we're trying to configure a clustered CAS 3.0.7 platform,
following the instructions at
http://www.ja-sig.org/wiki/display/CASUM/Clustering+CAS#ClusteringCAS-re
ferences
<http://www.ja-sig.org/wiki/display/CASUM/Clustering+CAS#ClusteringCAS-r
eferences>   .

	We connect to a webapp which redirects to the cas login url.
Once the login is done, cas redirects the user to the webapp page. cas
and the webapp are on the same tomcat ( 5.5).

	All is working flawlessly with a single-server environment, but
after having configured cas and tomcat to replicate sessions and tickets
among two server, we have this behavior:

	The user goes to http://oursite.domain.it /application
<http://oursite.domain.it/application>  . The application doesn't find a
suitable ticket, so redirects the browser to
https://oursite.domain.it/cas <https://oursite.domain.it/cas/login>
/login <https://oursite.domain.it/cas/login>  . The user logs in
successfully and cas tries to redirect the browser back to
http://oursite.domain.it <http://oursite.domain.it/application>
/application <http://oursite.domain.it/application>  , which find that
the given ticket is not valid because obtained from the remote server.
Shouldn't they be syncronized? What could be wrong? 

	With the same configuration, and shutting down one of the two
servers, all works fine.

	This is an extract from the log, on the server that grants the
ticket: 

	2007-08-21 11:52:07,947 INFO
[org.jasig.cas.authentication.AuthenticationManagerImpl] -
<AuthenticationHandler:
org.jasig.cas.adaptors.ldap.BindLdapAuthenticationHandler successfully
authenticated the user which provided the following credentials:
c.tassini at domain.it>

	2007-08-21 11:52:07,949 INFO
[org.jasig.cas.CentralAuthenticationServiceImpl ] - <Granted service
ticket [ST-3-tqk4bNPe05dvGmgaeJCkBidNCEvNOndyekq-server2] for service
[http://mysite.domain.it <http://mysite.domain.it/Application>
/Application <http://mysite.domain.it/Application> ] for user [
c.tassini at domain.it <mailto:c.tassini at domain.it> ]>

	And this is from the other server, contacted by the application
for validation:

	Aug 21, 2007 2:02:29 PM edu.yale.its.tp.cas.client.CASReceipt
getReceipt

	</cas:serviceResponse>

	]]]] was not successful.

	Any idea about what could be wrong? 

	Thanks in advance.
