While working with Grails and the Spring Security plugin, the current spring security filter chain is available in the springSecurityFilterChain bean. It is very easy with that to show what the current chain looks like so you can work through filter chain issues. I used the following code in the Grails Console plugin to get the bean:

def filterChain = ctx.getBean('springSecurityFilterChain')

Also if you want to poke around the other beans available this is a great post to check out: Spring Beans from the Grails Console .
