User management

Types of users: There are three types of uses

Business users: View results of business modeling

use client tools

Modelers: Define business models

use the information modeler of SAP HANA Studio

Administrators

• Manage SAP HANA Database+-
• Use the administration console of SAP HANA STUDIO

Authentication

To liable to log on to the system, users have to be authenticated currently there are two authentication types:

Database – internal authentication with user name and password.

External authentication via a third – party authentication provider

Internal Authentication

• Users are created in SAP HANA database only
• Authentication is handled by SAP HANA database via username/password combination
• Using External User Repositions for Authentications:
• SAP HANA database supports the mapping of users created in the SAP HANA database to external users via the Microsoft windows active directory or the MIT Kerberos network authentication protocol
• AS the preconditions, you have installed the relevant Kerberos client's software  form your operating system software package and SAP HANA database has been configured accordingly
• The users stored in the Microsoft active directory or the MIT Kerberos key distribution center can then be mapped to database users in the SAP HANA data box. For that purpose, specify the user principal name (UPN) as the external ID when creating the database user

Authorization

SAP HANA database provides its own authorization Service:

All authorizations on data all handled in SAP HANA data box

The user with which you log on to the system determines which database objects you on acumen and modify

Users can only perform operations for which they have been granted privileges

Exception: There are two default users created during installation, which have a fixed set of privileges each by default

User can have the following types of privileges

Privileges that were directly granted to them (“Direct privileges”.)

Privileges that were granted to notes that they belong to ( inherited privileges)
