Zimbra with on premise Single Sign-On using Keycloak

In this article you will learn how to install Keycloak and how to set-up Zimbra on Keycloak. Keycloak is an open source identity and access management solution developed by RedHat.

By using Keycloak you will be able to manage all your users from Keycloak and implement Single Sign-On. Keycloak offers SAML, OpenID, social login, multi-factor authentication and more.

The technology used in this article is SAML, an open standard for Single Sign-On. When using SAML an Identity Provider (IdP) will take care of user authentication after which users can use their applications without having to log-on to each of them separately. In SAML these applications are called Service Providers (SP).

Learning objectives:

  • How-to Install Keycloak on Ubuntu 20.
  • Understand that Keycloak is a SAML IdP out of the box.
  • Configuring Zimbra as a SAML SP on Keycloak.
