Thanks Nico.

I'm just thinking how that would work (if that would work for my situation).
I looking at this from a client -> gateway -> backend server  perspective.
The client should actually not be bothered by the need to initiate a new
security context with the gateway. That's what you indicate, right?
(The gateway may need the delegated credentials to initiate a new security
context to a second backend server (silentl failover)).
