Not able to login or add user

[karnamonkster]

Hi,
A newbie question, I have successfully installed the plugin to elasticsearch & Kibana Authentication plugin.
Made the changes in the elasticsearch.yml as per the README.
Added user root with password
Started ES & KIbana
Stuck at the login screen for Kibana.
Which password should i use?

TypeError: Uncaught error: Cannot read property 'search' of undefined
