1. Keycloak LDAP for Federated AI Training Environment Authentication


    To set up Keycloak with LDAP for federated authentication in an AI training environment, you'll need to integrate Keycloak with an LDAP server. The LDAP server will be responsible for storing and managing user information, while Keycloak will act as the authentication gateway, providing tokens to your applications for the authorized users.

    Here's an outline of how to accomplish this with Pulumi:

    1. Create a Keycloak instance: You would likely deploy Keycloak onto a virtual machine or as a container within a larger orchestration framework like Kubernetes.

    2. Configure LDAP User Federation: You will need to add and configure a user federation provider in Keycloak. This is how Keycloak will communicate with the LDAP server.

    3. Set up Role Mappers: Depending on the requirements, you might want to map LDAP roles to Keycloak roles to maintain consistent authorization patterns across your applications.

    4. Configure other potential mappers: Attribute, Group, and various Hardcoded mappers can be necessary depending on how you want to handle attributes and groups from LDAP in Keycloak.

    5. Secure your setup: It is crucial to configure and maintain secure communication between Keycloak and LDAP, enforce password policies, and configure SSL/TLS if necessary.

    You will need the pulumi_keycloak package, which allows you to set up and configure Keycloak resources via Pulumi. Make sure you have already set up Pulumi with the appropriate cloud provider and installed the pulumi_keycloak plugin.

    In the provided code, replace placeholders like "<your-ldap-connection-string>" with the actual values you intend to use.

    import pulumi import pulumi_keycloak as keycloak # Configure your LDAP connection settings. ldap_user_federation = keycloak.ldap.UserFederation( "ldap_user_federation", realm_id="<your-realm-id>", name="LDAP", enabled=True, bind_dn="<your-bind-dn>", bind_credential="<your-bind-credential>", users_dn="<your-users-dn>", connection_url="<your-ldap-connection-string>", vendor="<your-ldap-vendor>", username_ldap_attribute="uid", rdn_ldap_attribute="uid", user_object_classes=["inetOrgPerson", "organizationalPerson"], uuid_ldap_attribute="uuid", ) # If roles in LDAP should be mapped to Keycloak roles, configure a Role Mapper. ldap_role_mapper = keycloak.ldap.RoleMapper( "ldap_role_mapper", name="LDAP Role Mapper", realm_id=ldap_user_federation.realm_id, ldap_user_federation_id=ldap_user_federation.id, role_name_ldap_attribute="<your-role-name-attribute>", role_object_classes=["<your-role-object-classes>"], roles_dn="<your-roles-dn>", ldap_roles_dn="<your-ldap-roles-dn>", ) # If groups are managed in LDAP, configure a Group Mapper. ldap_group_mapper = keycloak.ldap.GroupMapper( "ldap_group_mapper", name="LDAP Group Mapper", realm_id=ldap_user_federation.realm_id, ldap_user_federation_id=ldap_user_federation.id, group_object_classes=["<your-group-object-classes>"], groups_dn="<your-groups-dn>", ldap_groups_dn="<your-ldap-groups-dn>", ) # Example for mapping a specific LDAP user attribute to Keycloak. ldap_user_attribute_mapper = keycloak.ldap.UserAttributeMapper( "ldap_user_attribute_mapper", name="LDAP User Attribute Mapper", realm_id=ldap_user_federation.realm_id, ldap_user_federation_id=ldap_user_federation.id, ldap_attribute="mail", user_model_attribute="email", ) # If a hardcoded role should always be assigned to LDAP users, configure a Hardcoded Role Mapper. ldap_hardcoded_role_mapper = keycloak.ldap.HardcodedRoleMapper( "ldap_hardcoded_role_mapper", name="LDAP Hardcoded Role Mapper", realm_id=ldap_user_federation.realm_id, ldap_user_federation_id=ldap_user_federation.id, role="default-role", )

    Replace the placeholders with actual details such as the LDAP connection URL, user DN, bind credentials, attributes, and object classes specific to your LDAP setup. These settings depend on the schema and configuration of your LDAP server.

    Please note that the above Pulumi program assumes you have already configured Keycloak and its realms either manually or through Pulumi. If you're starting from scratch, you will need to configure realms and clients as well, which can also be accomplished using the pulumi_keycloak provider.

    Remember that you must handle secrets like bind credentials securely, and they should not be hard-coded in your Pulumi program. Look into the Pulumi Config system or a secret store like AWS Secrets Manager, Azure Key Vault, or Google Secret Manager for production use cases.

    Lastly, after you've confirmed the configuration works as expected, you can use the Pulumi CLI to deploy these changes. Make sure that you have the correct access rights and that the Keycloak server is reachable from the environment where you run Pulumi.
