Hi Andy, A quick note about the message: that was a bug in the exception message, but the code is working as expected: if the wrapped SessionManager does not implement the SessionDAOAware interface, it cannot be injected with a SessionDAO. I have since fixed the message to be correct and committed this change, although the code logic has not been changed.
Also, make sure that you do this: sessionManager.sessionMode = native before you try to inject the SessionDAO. The above call will automatically substitute the ServletContainerSessionManager for a DefaultWebSessionManager implementation on the fly. This latter implementation does in fact implement SessionDAOAware and should readily accept SessionDAO instances that are passed through the securityManager.setSessionDAO(...) call. In the meantime, I'll try to create a unit test with the ShiroFilter to see I can accurately recreate your issue, but I've been strapped for time lately - if you could create one (if possible) and post it to a Jira issue, that would help a lot.
