> New Knox service to add custom auth headers in the response
> -----------------------------------------------------------
>
> Key: KNOX-2792
> URL: https://issues.apache.org/jira/browse/KNOX-2792
> Project: Apache Knox
> Issue Type: Sub-task
> Components: Server
> Reporter: Sandor Molnar
> Assignee: Sandor Molnar
> Priority: Major
> Fix For: 2.0.0

> Time Spent: 40m
> Remaining Estimate: 0h

> A simple REST service is needed to perform centralized authentication and
> authorization of incoming requests. Combined with nginx's external
> authentication capability it allows for every request to be checked for valid
> authentication before being forwarded to the upstream service.
> If a valid principal is found, a header is added to the response, by default
> {{X-Knox-Actor-ID}}, with the principal. In addition, if the authenticated
> subject has groups, these are added into comma-separated headers of the
> default form {{X-Knox-Actor-Groups-num}}. Each group header has a character
> limit of 1000 to keep them reasonably sized. The header names can be
> customized via configuration properties.
