Paul,

Spring security is a small convenience. Java CAS client can be configured 
without spring. https://github.com/apereo/java-cas-client

Hi,

I will try to describe the exact problem in detail as it is hard to sum up in 
the title.

We have a website and several other services that we are gonna protect with CAS 
5.3. The website uses Spring Security but we have to use a custom access 
control due to it's Vaadin nature. It's a SPA so we cannot rely on Spring 
Security's filter mechanism.

I would like to be able to login a user that is already authenticated via CAS 
when the user enters the website. Normally, the Spring Security 
CasAuthenticationFilter would jump in if a user wants to visit a guarded page 
but this is not the case. I understand I have to trigger that mechanism 
manually.

Does anyone has a suggestion what would be the best approach? Use the Java CAS 
Client and do more or less the same what the CasAuthenticationFilter is doing 
and implement it on my own?

Cheers,
  Paul
