Network Intents errors with CAS authentication

Description

If you are using legacy CAS authentication in NSP, you may encounter authorization errors when using Network Intents tools.

As a workaround for this problem, an Admin user can assign access permissions to Network Intent users through Keycloak:

1. Log into Keycloak: https://<NSP_system_IP_address>/auth   - admin / <admin_password>

2. Ensure that the realm is set to Nokia.

3. Under the manager section, click on Users.

4. Click on View All Users.

5. Click on the altiplano_admin user ID.

6. Click on Role Mappings.

7. Under Client Roles, click on NSP.

8. Select ALTIPLANO_ADMIN, ALTIPLANO_SYSTEM, ALTIPLANO_VIEWER, and SNMP_MGR_SYSTEM.

9. Click Add Selected.

10. Restart the nsp-mdt-ac-0 pod.
