To access the IBM Cognos server, login credentials are required. The credentials can be anonymous, or associated with a specific user.

When using an anonymous login, ensure that Allow anonymous access? is set to True in the IBM Cognos Configuration utility (Security > Authentication > Cognos > Allow anonymous access?). When using anonymous credentials, you can use the default CredentialsForLoginCognos DPM settings. For more information, see DPM settings for publishing data.

When logging in as a specific user, you must ensure that a Namespace is properly configured in the IBM Cognos Configuration utility (for example, you could create a new datacollection namespace under Security > Authentication).

The server must be restarted after making changes in the IBM Cognos Configuration utility.

After making the required IBM Cognos server updates in the IBM Cognos Configuration utility for a specific user, you must update the CredentialsForLoginCognos DPM setting (do not use the default settings). For more information, see DPM settings for publishing data.
