Docker Login Issue

[abhishek4794]

I have set up repository succesfully then I created one test user and gave him write-all rights through UI.
But whenever I am trying to login into my registry(localhost:5000) it is giving following error.
docker login localhost:5000
Username (test): test
Password: test
Error response from daemon: Get http://localhost:5000/v2/: unauthorized: authentication required

And in docker container logs I can see these logs :-
