How can we add an authority to GrantedAuthority at run time? really best approach

Hello all,

I have read a lot about this question e.g. here

http://forum.springsource.org/showth...ty-at-run-time

I doubt if this the best approach. We create a new authentication and fill it. What's the mater if I want to keep the old one origin? Do we have another approach to the extend or change the current SecurityContext on runtime?

best wishes
Jack

All fine now :)
