Every application server vendor is free to implement container security differently nor are they required to use JAAS. But, URL-based security is not a very clever mechanism and often can frameworo misused. The concept of Security Interception is key to protecting resources under Acegi.

Spring Security

Starting from the bottom, a FilterSecurityInterceptor is declared and passed both the authentication manager and the access decision manager. In the case of web applications, security interception is done using a servlet filter – SecurityEnforcementFilter — in combination with the FilterSecurityInterceptor. For help see solution 3 below. In order to use this securityContext, we need to add it to the list of context configuration locations in web. I used the mvn install: Tracing the chain of authorization, the security interceptor receives access to a protected resource.

Erik, Now, that it works. For example, an ADMIN user has unlimited access to application properties and can change or manipulate them—for good or for worse. From there, the method has two options, either return a fully populated Authentication object or throw an AuthenticationException.
