Help Document

Diagnosis

This client was originally a central system in a Central User Administration (CUA) or was created as a copy of a central system.
User only existed there for administrative purposes, and therefore had no system assignment for this client. The user therefore could not log on to this client.

System Response

User is still not permitted to log on.
Changes to this user therefore have no effect.

Procedure

Our recommendation for how to handle this warning depends on the future purpose of this client.

  1. If you are going to use the client as a CUA central system again in the near future, you can ignore this warning, since it will not be shown in a CUA central system.
  2. However, if you are going to continue to use this client as a standalone client or as a child system of a CUA, you can delete users of this type.

Use the report RSDELCUA to delete these users.
