Hi, @asatsi thx for creating this issue. We'll try to fix it in the next minor version. 
0. name suggestion EmptyPathAwareRedirectStrategy
1. please add a comment why we need this class
2. maybe extend DefaultServerRedirectStrategy with sendRedirect method override?
Simple login doesn't work with SERVER_SERVLET_CONTEXT_PATH 
**Describe the bug**
I have setup SERVER_SERVLET_CONTEXT_PATH as part of the deployment in Kubernetes. The ingress rule uses this URI. Everything works well if the spring AUTH ENABLED is not set. Once I enable the AUTH, the URL takes me to the default /login page instead of the $SERVER_SERVLET_CONTEXT_PATH/login page and fails to load.
