Role Management
Limit character set for user ID
Locking and validity of the user account is done through the user administrator and is also valid for other authentication procedures. This means that a login via SSO is not possible for an invalid user or a user with administrator lock. We therefore always recommend that you prevent access to the system by setting the validity of users. Setting validity on assigned roles also prevents the user from performing actions in the system, but does not generally prevent them from logging in.
If the programme determines that both of the criteria set out in the previous bullet points are met, the criterion of equality shall apply. This means that the proposed values of the permission that is already in place and to be added will come from the same transaction. Thus, the programme does not add a new default permission to the permission tree.
SU2X_CHECK_CONSISTENCY & SU24_AUTO_REPAIR
If you set the profile parameter dynamically, no users are logged out of the application server. You can prepare maintenance work in good time. The value 2 in the profile parameter does not prevent the login with the emergency user SAP*, if this is not set as user master record and the profile parameter login/no_automatic_user_sapstar is set to 0. You can also change the value of the parameter again at the operating system level. For details on the SAP user, see Tip 91, "Handling the default users and their initial passwords".
The S_RFCACL authorization object is removed from the SAP_ALL profile by inserting SAP Note 1416085. This notice is included in all newer support packages for the base component; This affects all systems down to base release 4.6C. The reason for this change is that the S_RFCACL authorization object, and especially the expression "total permission" (*), is classified as particularly critical for its fields RFC_SYSID, RFC_CLIENT and RFC_USER. These fields define from which systems and clients or for which user IDs applications should be allowed on the target system. Thus, the overall authorisation for these fields allows the login from any system and client or for any user and thus creates significant security risks.

The freeware Scribble Papers is a "note box" in which all kinds of data can be stored. It takes in typed texts as well as graphics and entire documents. The data is then organised in folders and pages.
, the creation of the derived roles is tedious - because SAP does not offer smart mass maintenance.
If the proliferation has occurred because the authorization concept was not adhered to, a cleanup is sufficient.
