Clustering with AD auth, ClearPass and a bad bean

Tue Jan 6 19:09:20 EST 2009

Thanks for getting back to me, Scott. (It's been a couple weeks I've been on vaca)

I copied our custom CAS source directory from one machine (the one that compiled the working, production CAS app 3.2.1 with ClearPass no clustering) to another machine, made the clustering changes and compiled a new war file. I followed the JA-SIG instructions for implementing clustering:

http://www.ja-sig.org/wiki/display/CASUM/Clustering+CAS

I compared the target directory on both machines and found these new jars on the clustering machine:

target/cas.clearpass-1.0-SNAPSHOT/WEB-INF/lib

cas-server-integration-jboss-3.1.jar
concurrent-1.3.4.jar
jboss-cache-1.4.1.GA.jar 
jboss-common-4.0.4.jar
jboss-j2ee-4.0.2.jar 
jboss-jmx-4.0.4.jar 
jboss-minimal-4.0.2.ja
jboss-serialization-1.0.3.GA.jar
jboss-system-4.0.2.jar
jgroups-2.4.1.jar
jta-1.0.1B.jar
ldapbp-1.0.jar
spring-2.0.6.jar *****
spring-ldap-1.1.2.jar *****
trove-1.0.2.jar

I can understand all of the new JBOSS jar files being added, but there is two new Spring jars. Do you think I'm the right path here? What would be the best way to go from here?

Thanks millions,

Andy

Apparently ClearPass is overriding a method its not supposed to:
Caused by: java.lang.VerifyError: class edu.csus.cas.clearpass.
ClearPassController overrides final method handleRequest.(Ljavax/servlet/http/HttpServletReques
t;Ljavax/servlet/http/HttpServletResponse;)Lorg/springframework/web/servlet/ModelAndView;

Maybe you changed Spring versions from what ClearPass was compiled with?

Hi all,

My name's Andy from Sacramento State.

I'm clustering CAS, and I think everything is fine with the cluster. I got CAS clustered in a test environment with plain vanilla CAS 3.2. But now I'm getting an exception on my test environment with the ClearPass mod and AD auth all set up (super close to our production setup) - see below. We're using the CAS ClearPass mod. Can anyone shove me in the right direction?
