Work Description: lmccay opened a new pull request, #1262:
URL: https://github.com/apache/knox/pull/1262
[KNOX-1234](https://issues.apache.org/jira/browse/KNOX-3347) - Introduce
TokenExchangePrincipal for extending Act claim for token_exchange
## What changes were proposed in this pull request?
Currently, the ActorChainPrincipal includes whatever act chain was in the
Subject token from the token_exchange. The presence of the
ImpersonatedPrincipal is currently only added by the identity assertion
provider based on a doAs and proxyuser based impersonation. This is required
for the new actor to be added to the nested 'act' claim.
Let's add the use of the TokenExchangePrincipal by the identity assertion
logic that sets the ImpersonatedPrincipal in addition to the doAs pattern.
We also have to keep the existing principal mapping logic intact so that the
token exchange reflects the mapped principal as appropriate even when not the
principal requested in the token_exchange request.
Also, be sure that the actor token is being properly validated.
## How was this patch tested?
Existing tests run and new tests added.
Manually tested as well.
