OnCommand Insight Data Warehouse (DWH) 7.3.3 and higher
The Data Warehouse installer creates Informix users in both local and on the domain when OCI DWH (Data Warehouse) is installed as Domain Administrator. By default, Cognos is configured to use only the local Informix user. However, some customers may have a requirement to use only domain users.
"Informix" users information and configuring domain user is also documented in our OCI Data Warehouse guide.
