Description Standa Laznicka 2019-09-10 13:25:51 UTC
Description of problem:
When RequestHeader IdP is configured for challenges, authentication requests fail because the oauth-server sets incompatible headers (Location and WWW-Authenticate).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. configure ReqeustHeader IdP as challenger
2. curl -k -H "X-Csrf-Token: 1" 'https://<oauth-server-host>/oauth/authorize?client_id=openshift-challenging-client&response_type=token'

Actual results:
Error: redirect header (Location: https://oauth-proxy-httpd.usersys.redhat.com/challenging-proxy/oauth/authorize?client_id=openshift-challenging-client&response_type=token) and challenge header (WWW-Authenticate: Basic realm="openshift") cannot both be set

Expected results:
Redirect to a server which will authenticate the user to openshift with a request with a required header
