IP-based roles without login screen

[Clemensl]

Update I have solved the problem, the DelegatingFilterProxy was missing in that project Please close
----------------


I am working on a new project where we want to assign Spring security roles according to their IPs and use those roles in the intercept-url 'access' command. That project will not have any interface, it's just a simple m2m machine.

The problem I have is that my access decision manager is not called (my ipAuthenticationEntryPoint isn't called either). It doesn't matter if I use <intercept-url pattern="/**" access="denyAll" /> or check with hasRole for the role, in both cases I can access any page and the access decision manager is not called...

Do you have any idea what's wrong or how I could accomplish what I want? It works flawlessly in one of my other projects, but there I have a normal login screen etc.

Thank you in advance
