Feature Request - Follow User Federation Redirection

[vikas027]

I have configured Jenkins to authenticate (in my test environment) with Keycloak. following this wiki.

Thus, my Jenkins URL gets redirected to Keycloak URL
Jenkins URL: http://192.168.0.15:8080
Keycloak URL: http://192.168.1.77

Now, when I try to connect Jenkins using my Jenkins credentials, I encounter below error

F, [2017-07-18T23:53:19.872212 #58520] FATAL -- : JenkinsApi::Exceptions::Unauthorized: Invalid credentials are provided.

        from abc.rb:23:in `<main>'

It might sound absurd, but is this something which can be handled thru the API client?
If yes, please take this as a feature request. If not, feel free to close the issue :)
