> For some links(such as "/jmx, /stack"), blocking the links in filter chain 
> due to impersonation issue is not friendly for users. For example, user "sam" 
> is not allowed to be impersonated by user "knox", and the link "/jmx" doesn't 
> need any user to do authorization by default. It only needs user "knox" to do 
> authentication, in this case, it's not right to  block the access in SPNEGO 
> filter. We intend to check impersonation permission when the method 
> "getRemoteUser" of request is used, so that such kind of links("/jmx, 
> /stack") would not be blocked by mistake.
