Mass locking and end validity date of users

User lock

There are 2 good reasons for mass locking and ending validity date of user: security and licenses.

Questions that will be answered in this blog are:

  • How can I mass lock users automatically if they have not logged on for a certain time?
  • How can I mass set the validity date of the users that did not log on for a certain time?

Automatic lock of user after expired logon

In RZ11 you can set parameter login/password_max_idle_productive with an amount in days.

Password max idle initial

If the user (including yourself) did not logon to the system after this amount of days the password is still valid, but it does not allow you to logon.

If the user tries to logon after the period he will see this error message and cannot continue:

Password deactivated

In SU01 such a user looks like this:

Password expired

If you also want to automatically lock users after you give them a new password, use the parameter login/password_max_idle_initial.

Initial passwords is one of the nice ways of entering a system as hacker. Especially if the initial password used by the admin is more or less the same (like Welcome_1234!). Countermeasure: instruct your admins to use the Password Generator. This will generate long random once off password.

Mass setting of user validity date

For user measurement and security reasons you want to limit the validity period as well. Users who are locked still count for user measurement (see blog on license measurement tips & tricks). Users locked and unlocked by some method can be security threat.

Standard SAP program RSUSR_LOCK_USERS (built on top of program RSUSR200) is the tool to achieve this.

It has quite a long selection screen:

RSUSR_LOCK_USERS screen 1

On the first block set the dates for last logon and password change to get a good selection of users.

RSUSR_LOCK_USERS screen 2

On the second block very important to only select Dialog Users.

First run with Test Selection to get a list. If you are happy with the list, run it with Set End Of Validity Period.

Performance and bug notes (OSS search hints RSUSR200 and RSUSR_LOCK_USERS): 
2615606 - SUIM | Search for users with incorrect logon does not work
2628060 - SUIM | RS USR200: Poor performance
