  - User Administration
    After you install Keycloak, you must consider how the software manages users and authentication.
    - Default User Administration
      Keycloak uses the concept of a realm to manage and authenticate users. When you install the Keycloak server, a realm called testserver is created for you in Keycloak. All server users belong to this realm and when they log in to the server, they log into that realm.
    - LDAP User Authentication
      You are using a Lightweight Directory Access Protocol and Active Directory HTTP server to manage users and authentication. You want to know the best practices to use that LDAP/AD server to manage user access to Link.
    - Runtime REST API

Connecting Runtime REST API server

This topic documents how to set up connection between Keycloak and Runtime REST API server.

Procedure

Install Link or Runtime & Monitoring.
In Keycloak, make sure that Keycloak Auth Enabledis set to true.

In text editor, open tx-rest.properties to confirm the connectivity information. You can see the below information and update as appropriate to your environment:

#Flag indicating whether Keycloak is enabled for identity & access management
authentication.keycloak.enabled=true
#Keycloak specific properties
authentication.keycloak.serverUrl=http://localhost:8080/auth
authentication.keycloak.realmId=link
authentication.keycloak.clientId=link-runtime-rest
authentication.keycloak.clientSecret=9465403f-0ae6-4cfd-98fb-ecdf8c4485ed

Run Runtime REST API server to service REST client calls.
REST clients invoking the Runtime REST API should include the user credentials that can be authenticated with Keycloak to run the maps or flows, or to fetch any runtime information.
