Authentication/SAML
Zimbra Single Sign-On using SAML
Did you know that Zimbra supports SAML single sign on? SAML is an open standard that allows you to have a single login page for all applications in your organization. SAML is a Zimbra Network Edition feature. Once you have set-up SAML you can easily add Multi Factor Authentication.
Zimbra is a SAML service provider and should work with most SAML identity providers. For a number of SAML identity providers we have provided set-up guides which can be found in the Zimlet Gallery using this link: https://gallery.zetalliance.org/extend/category/saml and below:
