Single sign-on (SSO) allows users to authenticate against your Identity Provider (IdP) when logging into the Pantheon Dashboard. For more information, see SSO and Identity Federation on Pantheon.
SAML SSO is included for customers with Diamond Support, and is available for purchase for Pantheon Organizations with Platinum or below. SAML is an organization-wide feature only and is not available on a per site or per environment basis. If you'd like to upgrade to an eligible support package, please contact Sales. Agencies interested in SAML SSO should reach out to their Partner Manager to see if they qualify. You must be part of the Pantheon Partner Program to qualify.
Pantheon organization administrators can manage sites and teams with the Organization Dashboard. Automated user provisioning isn't available.

Date/time to enable: A time you'd like Pantheon to enable SSO, when you can test and ensure everything works.
If you are a member of a SAML-enabled organization, and the password field does not disappear after you enter your username and password, you'll need to log out of your active session, log back in, and try again. This can occur if you have two accounts with different email addresses and have not logged out of an active session.
Google account login is disabled for users in organizations using single sign-on. SAML allows organizations to centrally manage authentication policies, so allowing social login could circumvent that policy.
Make sure you generate the certificate using the right encoding.
There are 3 types of certificate that you can generate:
