An administrator needs to add users from multiple authentication providers to a single role.

In the Cognos Analytics user interface, authentication providers are represented by namespaces.

Cognos Analytics supports the following types of authentication providers:

Active Directory

Custom Java Provider

IBM Cognos Series 7

LDAP

OpenID Connect

SAP

SiteMinder

Authentication providers are configured in IBM Cognos Configuration, under the Security > Authentication category. After the provider namespace is added there, and the IBM Cognos service is restarted, the namespace name is displayed in Manage > Accounts, and users can log on to Cognos Analytics using that namespace.
