Federate oVirt engine authentication to OpenID Connect infrastructure

In this post I will introduce how to integrate OIDC with oVirt engine using Keycloak and LDAP user federation.

Prerequisites: I assume you have already setup the 389ds directory server, but the solution is very similar for any other LDAP provider. As OIDC is not integrated into oVirt directly, we use Apache to do the OIDC authentication for us. The mod_auth_openidc module nicely covers all needed functionality.

Overview

Integrate with external OpenID Connect Identity Provider (IDP) to provide Single Sign-On (SSO) across products that use the IDP for authenticating users. We currently have oVirt SSO for providing unified authentication across Administrator and VM portals. The oVirt engine SSO also provides tokens for REST API clients and supports bearer authentication to reuse tokens to access oVirt engine RESTAPI. With external IDP integration the internal oVirt SSO is disabled and browser users will be redirected to the external IDP for authentication. After successful authentication users can access both Admin and VM portals as they normally do. REST API clients don't have to change, they can still obtain a token from engine SSO and use the token for bearer authentication to access oVirt engine RESTAPI. Engine SSO acts as a proxy obtaining the Continue reading

Integrating Kibana/Elasticsearch on Top of OpenShift with oVirt Engine SSO

oVirt Engine provides a powerful way to manage users and domains using the oVirt Engine AAA extensions. oVirt Engine supports many different LDAP server types for authentication using the ovirt-engine-extension-aaa-ldap extension and supports managing internal users using the ovirt-engine-extension-aaa-jdbc extension. Clients can use the powerful oVirt Engine user management in their applications by using the OAuth2 or OpenId Connect end points provided by oVirt Engine SSO to authenticate users in their applications.

Below is step-by-step instructions on how to integrate Kibana/Elasticsearch on top of OpenShift with oVirt Engine SSO. The instructions should work for any client application that can be configured to use a OAuth2 or OpenID Connect server to authenticate its users.

The goal is to integrate Kibana/Elasticsearch on top of OpenShift with oVirt Engine SSO, so existing engine users can access Kibana/Elasticsearch without reauthentication (we don't need to maintain authentication configuration separately for oVirt Engine and Kibana/Elasticsearch).

The integration requires a fully working and configured oVirt Engine instance on oVirt Engine host and a fully working and configured instance of Kibana/Elasticsearch on top of OpenShift on the OpenShift host.

Installing Kibana/Elasticsearch and OpenShift Backend

Install Kibana/Elasticsearch/OpenShift on CentOS7 or RHEL 7.3 as described in https://github.com/ViaQ/Main/blob/master/README-mux.md
