Which user is NOT created during the installation of SAP HANA?

During the installation of SAP HANA, certain predefined users are created as part of the system setup. The user "sidadm" is the system administrator for the SAP HANA database that allows management of database operations and tasks. The user "sapadm" serves as a primary user for administrative tasks across the SAP landscape.

The "SYSTEM" user is a default user account that has a full set of privileges and is responsible for managing the overall system operations, including creating and managing other users and roles.

In contrast, the "admin" user is not a predefined user that gets created during the installation process. While it might be a name that one might intuitively expect to be part of a user setup, it doesn't exist in the standard user creation during the SAP HANA installation. This distinction is crucial for understanding the typical user accounts present in SAP HANA and their respective functions within the environment.
