Hi again,
I forgot to explain the daemon issue. If you are not installing EMS from yum/apt than you have to manually create that user on your system.
here is a tutorial on how to install EMS from yum/apt:

Also, the documentation contains explanations regarding the error you are seeing (id: evostream: No such user)
Best regards,
