> Unix authentication seems to be not working. 
> Steps to reproduce
> -- Set the Authentication method as Unix
> -- Add a unix user
> -- Make sure the user is synced to Ranger (verify in users page)
> -- Try logging in as the user.
> It just says username/password is not correct.
> Increasing the debug level shows there is this exception.
