Authorizations in SAP systems: what admins should look out for
Service User
In the SAP system, passwords are locked when the maximum number of allowed password login errors is reached. This counter is reset with a password each time you successfully log in. In addition, an initial password can be locked when its validity has expired. Both the validity of the initial password and the maximum value for password login errors are set using profile parameters. For details, see Tip 4, "Set password parameters and valid passwords characters". A password lock only prevents a user from logging in via his password, because the number of errors is only evaluated if the login is done by password. If a login is now made via other authentication methods (such as SSO), these are not affected by the password lock. This also applies to internal expiration procedures (such as background jobs) because you do not need to register a password. This prevents, for example, denial-of-service attacks, which first cause a password to be locked in order to block internal processes. Eine Ausnahme von dieser Regel gibt es allerdings: Auch wenn andere Authentifizierungsverfahren genutzt werden, prüft das System, ob der Benutzer dazu in der Lage ist, sich mit einem Passwort anzumelden. Wenn dies der Fall ist und das Passwort gerade geändert werden muss, wird diese Änderung vom Benutzer abgefragt. Diese Abfrage können Sie aber auch mithilfe des Profilparameters login/password_change_for_SSO ausschalten.
Note that the SAP_NEW_ individual profiles should be retained themselves, so that at any given time, traceability is ensured as to which release and which permission was added. For more information, see SAP Notes 20534, 28175, and 28186. SAP Note 1711620 provides the functionality of an SAP_NEW role that replaces the SAP_NEW profile. If you have added this note, the profile will no longer be used. Instead, you can generate your PFCG role SAP_NEW by using the REGENERATE_SAP_NEW report. When you call the report, in the source and target release selections, type in the appropriate fields, and the role is created for that release difference.
Implementing CRM Role Concept for External Services
You would like to revise your authorisation concept and tailor SAP roles only to the productive processes. We show you how to use the statistical usage data from the Workload Monitor for the SAP role definition. One of the biggest effort drivers in redesigning SAP role concepts is the definition of transactional expression of SAP roles. By using the statistical usage data from the workload monitor, you can avoid costly coordination with process managers in the sense of a Green Field Approach. In this way, you can tailor your SAP role concepts to the content of the usage behaviour. The only requirement is that the data be available for a representative period. This is two months in the SAP standard; You can also extend this time period. Below we describe how you can use the statistical usage data from the Workload Monitor for the SAP role definition.
The generic entries cause deletions in the target system if the same entries originate from both development systems. To prevent this, insert SAP Note 1429716. Then use the report SU24_TRANSPORT_TABLES to transport your SU24 data. This report creates a detailed transport BOM based on the application names. Since the report has significantly higher maturities than step 3 of the transaction SU25, we advise you to apply this report only in a Y-landscape.
During go-live, the assignment of necessary authorizations is particularly time-critical. The "Shortcut for SAP systems" application provides functions for this purpose, so that the go-live does not get bogged down because of missing authorizations.
Obsolete but critical functions are disabled by some security precautions; in such cases, you do not need application testing.
At www.sap-corner.de you will also find a lot of useful information on the subject of SAP authorizations.
You have read that it is possible to perform mass activities, such as mass roll-offs, using standard means.
