> AuthenticationFilter.doFilter is called twice (not sure if that is intentional or not).
> The second time it is called the ServletRequest is already authenticated, i.e. httpRequest.getRemoteUser() returns non-null info.
> If the kerberos authentication is triggered a second time it'll return a replay attack exception.
> I solved this by adding a if (httpRequest.getRemoteUser() == null) at the very beginning of doFilter.
> Alternatively one can set an attribute on the request, or figure out why doFilter is called twice.
