I'am new in Spring Security, I have many problems to configure Spring Security with CAS SSO, my project is composed by:
Glassfis v3 as application Server on Centos 5.5.
Application A: layer client implemented with Silverlight
Application B: Bussines layer implemented with Java, it exposes bussines logic as webservices.

I'am using Spring Security with CAS to provide Single Sign On, first time I request an application A resource, CAS login form appears, login is successfull and requested resource is displayed, everything is OK. Problems appears when requested resource call an application B webservice no response is get. I think that problem comes from bad authetication on application B resource.
This is a typical arquitecture so implementing SSO with CAS has to be a well know problem with solution.

We have been looking every where in internet, and we have done a lot of tries with no success, every thing seems to be ok but it doesn't work.

Un example showing how to configure this kind of applications it would be appreciated
