I had this problem.. The documentation is not complete..
I solved this problem and I documented it on my blog: http://localhost8080.blogspot.com.br/2013/07/jboss-as-7-cluster-sso.html
My blog is in portuguese.. if you have any trouble, let me know.
thanks you for quick response, but my problem is:
do we have to use SSO when we cluster servers, without sticky session and when application is secured?
It looks like authentication data is not replicated with session without SSO.
The problem is not with SSO configuration.
I'm asking if there is possibility to replicate authentication data without SSO.
I'm having the same difficulty, found a solution?
