- Keycloak
  This documentation describes about the Keycloak functionality.

  - Installation
    To install Keycloak refer to the latest “Getting Started” documentation available on the Keycloak product website.
  - User Administration

    - 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.
      - Selecting LDAP provider in Keycloak
        You can use the Keycloak Admin Console to add an LDAP/AD provider.
      - Required settings for a successful connection to your LDAP/AD provider
        The form includes many fields and several fields include default values.
      - User synchronization
        You must import all users from your LDAP/AD user database by using the option to Synchronize all users. Users are imported based on your saved settings when you set up your LDAP/AD provider.
      - Mappers
        Keycloak uses mappers to map the user attributes defined in the Keycloak user model such as username and email to the corresponding user attributes in the LDAP/AD user database. By default, when you saved your settings and created your LDAP/AD provider, the following mappers were created.
    - Runtime REST API
      Runtime REST API supports Keycloak authentication of user credentials for running maps and flows. Like Link, Runtime REST API can be configured to authenticate users with Keycloak.

Mappers

Keycloak uses mappers to map the user attributes defined in the Keycloak user model such as username and email to the corresponding user attributes in the LDAP/AD user database. By default, when you saved your settings and created your LDAP/AD provider, the following mappers were created.

The username attribute that you specified in the Username LDAP attribute must match the username attribute defined in the Keycloak mapper for the LDAP/AD user database to connect with Keycloak.

If you change the Username LDAP attribute from the default value cn to userPrincipalName, Keycloak would make the same change in the mapper called username to match.
