How to Lock/Unlock a User in SAP

Locking a user


Purpose of locking user is to temporarily deactivate the users so that they cannot longer access the system.

Users can be locked in 2 ways:-
  • Automatically
  • Explicitly/Forcefully

Automatically:- There are two possibilities when users get lock automatically
  • Maximum number of failed attempts:- controlled via the parameter login/fails_to_user_lock .If value is set to 3 it means after 3 failed attempts user will be locked.
  • Auto unlock time:- "login/failed_user_auto_unlock" defines whether user locked due to unsuccessful logon attempts should be automatically removed at midnight.

Explicitly/Forcefully: We can lock and unlock users in 2 ways-
  1. Lock single user (SU01)
  2. Lock multiple user (SU10)
