> Project: Apache Knox
> Issue Type: Bug

> Time Spent: 10m
> Remaining Estimate: 0h
>
> KNOX-3321 provided an initial implementation for 8693 and adding an 'act'
> claim to the returned JWT based on the presence of the ImpersonatedPrincipal
> and having delegated auth enabled on the KnoxToken service.
> This falls short of what we need to support token exchanges that already
> include an 'act' claim in the subject token. To support this properly, we
> need the previous 'act' claim represented in the Java Subject with the full
> chain represented. We will then add the next actor subclaim to the chain from
> within the KnoxToken service, effectively continuing the chain as it flows
> through the actors for the given request.
> To support this, we should introduce a new principal called
> ActorChainPrincipal which will have an extended interface to provide the list
> of 'act' claims within the presented token for building out the chain in the
> new token.
