You can configure the IBM® Cognos® TM1® server to use IBM Cognos security for authentication instead of the default standard TM1 authentication.
To successfully complete these procedures, your IBM Cognos server must not be configured to allow anonymous access. If anonymous access is enabled on the IBM Cognos server, you cannot logon to a namespace from TM1 when importing Cognos groups into TM1.
To enable IBM Cognos security authentication on the IBM Cognos TM1 server, you must add or modify several configuration parameters in the server's Tm1s.cfg configuration file.
