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.

This is determined by the function block and not by the developer.

Even the best authorization tools cannot compensate for structural and strategic imbalances.
