Zimbra with Single Sign-On using Cisco Duo

By: zimbra

In this article you will learn how to set-up Zimbra on Cisco Duo. Cisco Duo is a cloud based identity and access management solution developed by Cisco. Cisco Duo focusses on Two-Factor Authentication (2FA) and integrations with on premise Active Directory, and cloud based SAML IDP's such as Azure AD, AD FS, Google, Okta, OneLogin, Ping or any other SAML 2.0 Identity Provider. Cisco Duo calls these integrations Authentication Sources.

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).

Cisco Duo is a SAML IdP and Zimbra is a SAML SP.

Learning objectives:

  • How-to Install set-up Active Directory in Cisco Duo.
  • Configuring Zimbra as a SAML SP on Cisco Duo.
  • Understand you do not need Active Directory to use Zimbra with Cisco Duo
