Modifying the authentication mechanism

To modify how IBM Spectrum Control authenticates users and user groups, configure the authentication repository.

Before you begin

You must be assigned the Administrator role to modify the authentication repository and manage role and group assignments.

About this task

The authentication mechanism determines how IBM Spectrum Control authenticates users and the user groups that are available for assigned roles. During the installation process, the WebSphere Application Server Liberty is configured with federated repositories. By default, authentication is configured to use the federated repositories, which contain a file repository and an operating system repository. The operating system repository includes the operating system users and groups that are defined on the server where IBM Spectrum Control is installed. For a server that is a member of a Windows domain, the operating system repository also includes the users and groups that are defined in that domain.
Important: WebSphere Application Server Liberty cannot resolve users or groups that are present in more than one repository in the federated repositories framework. Because of this limitation, you must select either the operating system repository or the LDAP repository for user authentication and authorization in IBM Spectrum Control. If you upgraded from an earlier version of IBM Spectrum Control with both the operating system repository and an LDAP repository configured, you can keep using both repositories. However, it is recommended that you select either the operating system repository or the LDAP repository.
