Looking at the SEAM 1.1.5 documentation, and the SeamLoginModule - it's able to call a custom method as long as it's boolean (java.lang.String username, java.lang.String password, java.util.Set roles) This only works for username/password type authentication.. It would be nice if there was an extended method signature that allowed passing in on the HttpServletRequest ie.. Something like boolean (HttpServletRequest request, HttpServletResponse response, Set roles); the above is pretty useful when using it with single sign on systems (which usually pass tokens through a cookie, or a URL parameter, or even rig up some support for SPNEGO).
