Hi Pedro,
Make sure that the standard password for user TMSADM has been changed in client 000 and delete this user in any other client. SAP Note 1414256 describes a support tool to change the password of user TMSADM in all systems of the transport domain.
SAP Note https://service.sap.com/sap/support/notes/1552894[1552894] shows how to update the report RSUSR003 to show the status of user TMSADM.
Regards,
V Srinivasan
