is is possible to override the default security manager in the web filter ?

[David Higginbotham]

I'm trying to use the ShiroFilter. I'd like to extend the default
security manager and start up this new security manager in the filter.
Is this possible ?

securityManager = domain.mystuff.MySecurityManager
securityManager.sessionMode = native

As far as I can tell this is being ignored. I always get an instance of
the DefaultSecurityManager.

Thanks,

David
