Add Enviroment variable which will show the Bcms login or will redirect to Login NCBI
We need to add an environment variable toggle that redirects to LoginNcbi component instead of Login component when a user is not logged in: . This way the coko site can still have existing login method, but ncbi deployed site will check for the myNcbi cookie and redirect to federated login.
Also, take care of an unhandled situation where myNCBI cookie expires
