Creating TM1 users when using Cognos security
When the IBM® Cognos® TM1® server is configured to use Cognos authentication, you cannot create new clients directly on the Cognos TM1 server.
Instead, all client administration is performed in Cognos security.
When a Cognos user accesses Cognos TM1, the user is validated and automatically assigned to the appropriate Cognos TM1 groups. There is no need to manually assign users to groups in Cognos TM1.
