System administrators can forbid passwords or password strings by entering them in the table USR40. This is useful, for example, to avoid the use of passwords which start with similar words as the name of the company, the river that crosses nearby, and so forth. Table USR40 is maintained with standard table maintenance transactions such as SM30 and SM31 (System Services Table maintenance). To specify a nonpermitted password string, you can enter the typical wildcards, * and , where the * substitutes a group of characters, and the , a single character. Figure 9 7 shows an example of this table with some of the forbidden password strings. In this example, all passwords starting with the characters SAP, containing R3, or ending with 2000 are forbidden. This table is client independent and, therefore, the password restrictions are applied to any system client.

The SAP R/3 system includes in the default installation two special users: DDIC and SAP*. These users have special privileges and must be protected to avoid unauthorized access. System administrators should consider a good strategy for managing the superusers of R/3 for security reasons and to ensure system integrity. The standard installation creates the system clients 000, 001, and 066. The SAP* and DDIC users are created in clients 000 and 001 with standard names and passwords.

SAP* is the standard SAP system superuser, and it's the only system user who does not require a user master record because it's defined in the code itself. When a new client is created for doing a client copy, SAP* is created by default in the new client with a standard password PASS and unlimited access rights. In the standard installation, SAP* has the password 06071992 in clients 000 and 001. The special properties of the SAP* user can be deactivated. To deactivate the properties of the SAP* superuser, you must create a user master record for it, in which case it will have just the authorizations given in the profiles of the user master record. If a user master record exists for SAP* and then it is deleted, it recovers the special properties assigned by the system code and has the password PASS again. When SAP* does not have a user master record, the password is always PASS; it cannot be changed, and it's not subject to any authorization check. Some of the measures to protect SAP* are as follows: Change the password in client 000 and 001. Create a user master record for SAP* in 000, 001, 066, and the possible new clients you create in the system. Turn off the special status of SAP* by setting the instance profile parameter login / no_automatic_user_sapstar to a value greater than zero in the common default profile, DEFAULT.PFL. If the parameter is set, then SAP* has no special default properties. If there is no SAP* user master record, then SAP* cannot be used to log on. Be sure to have a user master record for SAP* even when this parameter is set because, if the parameter is reset to the value 0, the system will again allow the logins by SAP* with the password PASS. Having a user master record, SAP* behaves like any other user subject to authorization checks. Its password can be changed. Create your own superuser account in each system client. This is explained in the next section. Delete all profiles from the SAP* profile list so that it has no authorizations. Be sure that SAP* is assigned to the user group SUPER which protects the master records from being deleted by anyone not having authorization to delete SUPER master records. The user group SUPER has special status in the user maintenance profiles as delivered by the system. Users within this group can only be maintained or deleted by new superusers, as defined by the SAP standard authorization profiles.
