===== Users and authorizations =====

  Redpeaks will connect remotely to your systems by using a dedicated user on each system. To create those users is a prerequisite.

**[[..:..:6.8:installguide:setupusers|MUST READ : User creation details]]**

**NetWeaver - ABAP:**
  * Redpeaks uses a **Communications data** user associated with the [[https://agentil.box.com/s/7wg9iazwq6839joo6i3y5dp53p1ha3bq|provided authorization profile]]\\
  * In most cases, user can be created in client 000. But sometimes access to target client must be necessary as well.
**NetWeaver - SAPControl:**
  * Redpeaks uses SAPControl web services to collect information on the system.
  * The access to these services can be either without authentication, or controlled by using an OS user similar than [SID]adm, see [[https://launchpad.support.sap.com/#/notes/ 927637|Note 927637]]
  * Look for the section describing the use of **service/protectedwebmethods**, make sure to allow the access of all **Getter/Reader** services
**HANA:**
  * SQL user associated with MONITORING role​
**BusinessObjects:** ​
  * User access to CMS repository and CMC portal
