I have my authentication type set to AUTH_TYPE = AUTH_DB, I follow instructions for creating an admin user with: fabmanager create-admin --app superset. I start the server as demon using supervisor and when I try to login I get invalid login. When I run the server from command line with superset runserver and try to login my credentials work.
May be when you are using supervisior, superset is not taking superset configuration file which causing it to use sql database instead of mysql.
