Chapter 3. Red Hat Decision Manager roles and users

To access Business Central or KIE Server, you must create users and assign them appropriate roles before the servers are started.

The Business Central and KIE Server use Java Authentication and Authorization Service (JAAS) login module to authenticate the users. If both Business Central and KIE Server are running on a single instance, then they share the same JAAS subject and security domain. Therefore, a user, who is authenticated for Business Central can also access KIE Server.

However, if Business Central and KIE Server are running on different instances, then the JAAS login module is triggered for both individually. Therefore, a user, who is authenticated for Business Central, needs to be authenticated separately to access the KIE Server (for example, to view or manage process definitions in Business Central). In case, the user is not authenticated on the KIE Server, then 401 error is logged in the log file, displaying Invalid credentials to load data from remote server. Contact your system administrator. message in Business Central.

This section describes available Red Hat Decision Manager user roles.

Note

The admin, analyst, and rest-all roles are reserved for Business Central. The kie-server role is reserved for KIE Server. For this reason, the available roles can differ depending on whether Business Central, KIE Server, or both are installed.

  • admin: Users with the admin role are the Business Central administrators. They can manage users and create, clone, and manage the repositories. They have full access to make required changes in the application. Users with the admin role have access to all areas within Red Hat Decision Manager.
  • analyst: Users with the analyst role have access to all high-level features. They can model projects. However, these users cannot add contributors to spaces or delete spaces in the Design → Projects view. Access to the Deploy → Execution Servers view, which is intended for administrators, is not available to users with the analyst role. However, the Deploy button is available to these users when they access the Library perspective.
  • rest-all: Users with the rest-all role can access Business Central REST capabilities.
  • kie-server: Users with the kie-server role can access KIE Server (KIE Server) REST capabilities.

3.1. Adding Red Hat Decision Manager users

Before you can use RH-SSO to authenticate Business Central or KIE Server, you must add users to the realm that you created. To add new users and assign them a role to access Red Hat Decision Manager, complete the following steps:

  1. Log in to the RH-SSO Admin Console and open the realm that you want to add a user to.
  2. Click the Users menu item under the Manage section.

    An empty user list appears on the Users page.

  3. Click the Add User button on the empty user list to start creating your new user.

    The Add User page opens.

  4. On the Add User page, enter the user information and click Save.
  5. Click the Credentials tab and create a password.
  6. Assign the new user one of the roles that allows access to Red Hat Decision Manager. For example, assign the admin role to access Business Central or assign the kie-server role to access KIE Server.

    Note

    For projects that deploy from Business Central on OpenShift, create an RH-SSO user called mavenuser without any role assigned, then add this user to the BUSINESS_CENTRAL_MAVEN_USERNAME and BUSINESS_CENTRAL_MAVEN_PASSWORD in your OpenShift template.

  7. Define the roles as realm roles in the Realm Roles tab under the Roles section.
  8. Click the Role Mappings tab on the Users page to assign roles.
