Hi, anyone had success CASifying Confluence 5 with Jasig CAS client ?

Following Jasig guide gives browser endless bouncing loop between CAS and Confluence.

There is implementation of JASIG CAS Client for Confluence 5.0 in this pull request. You should be able to build it using

mvn package -pl cas-client-core,cas-client-integration-confluence-v5

Sorry for late reply, I was busy on other subject.

Yes, it works, well, maven build fails with missing jar dependency:

[ERROR] Failed to execute goal on project cas-client-integration-confluence-v5: Could not resolve dependencies for project org.jasig.cas.client:cas-client-integration-confluence-v5:jar:3.3-SNAPSHOT: Failure to find javax.activation:activation:jar:1.0.2 in was cached in the local repository, ...

But after adding this jar to repo, it builds fine, and it works fine.

Thank you !

How do I patch this onto java-cas-client/cas-client-integration-atlassian?

Hi, all

It works well with Confluence v5.1.5 using cas-client-integration-confluence-v5-3.3-SNAPSHOT.jar.

But, there's a problem in my scene:

if the CAS user is not added in Confluence, when the user try to login, it causes redirection loops as below:


http://casServer/cas/login?service=http%3A%2F%2F confluenceServer%2Fhomepage.action


And, it shows getUser failed in debug log, because the user is not exists in Confluence.

Is there's a way to handle such scene?

Can u send the jar file to me? cas-client-integration-confluence-v5-3.3-SNAPSHOT.jar

I've tried it briefly - and yes there are some changes in Confluence classes causing exception.

Hi Jozef, as you mentioned in another reply, Jasig CAS client build from sources snapshot is required, so I compiled 3.3 build, but I'm not sure if there any configuration changes required for 3.3 ? The only thing I changed is authenticator class in seraph-config.xml to "Confluence35CasAuthenticator", but it still does not work.

This is the exception I get the first time I visit CASifyed Confluence 5:


javax.servlet.ServletException: Filter execution threw an exception
at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(

caused by: java.lang.IllegalAccessError: tried to access method<init>(Ljava/lang/Object;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)V from class org.jasig.cas.client.integration.atlassian.Confluence35CasAuthenticator
at org.jasig.cas.client.integration.atlassian.Confluence35CasAuthenticator.getUser(

And if I refresh the page with this error, I'm logged in. I'll try to look in the logs to see what's going on.

SO at this point your configuration is correct and you stumbled on that exception I've mentioned in my first comment. There is changed API in event dispatching - so at the first time your login failed (but is stored already), the second time no loginevent is dispatched - so you are in.

The change in JASIG cleint would be easy, if there where not messed dependencies (as supporting both JIRA and Confluence in 2 different versions). I have plan to split it to separate plugin, but haven't got to it yet.

Thank you for explanation. In the meantime do you think any workaround is possible to get it work nicely without this additional "Refresh" page action ?

Hi Jozef and evaldas,

I'm new to this process. Here is the steps I have done last night but did not work.

git clone

cd java-cas-client

mvn package -pl cas-client-core,cas-client-integration-atlassian

cp cas-client-integration-atlassian/target/cas-client-integration-atlassian-3.3-SNAPSHOT.jar /deploy/AppServers/techwiki/webapps/ROOT/WEB-INF/lib

cp cas-client-core/target/cas-client-core-3.3-SNAPSHOT.jar /deploy/AppServers/techwiki/webapps/ROOT/WEB-INF/lib

Did you patch configuration files appropriatelly according guide?
