Create the Calendar Server runtime user and group under which Calendar Server will run as follows:
Add icsgroup (or the value you selected) to the /etc/group file.
Add icsuser (or the value you selected) to the /etc/passwd file.

You must provide the user and group names when you Run Postinstallation Configuration Programs.
