SSO Google (SAML 2)

Before you get started

We support the 2 authentication protocols OAuth 2.0 and SAML 2.0 for Google Identity Platform. The following document provides the necessary information to set up a single sign-on between Google Identity Platform and LUCCA solutions via the SAML 2.0 protocol.

Here is the help page for implementing the OAuth 2.0 protocol.

Step 1: Creating the configuration in Lucca

This operation must be performed by an administrator or a user with access to the "Authentication and SSO parameters" module.

Once the application has been created, it needs to be activated for all users.

Note: activation may take several hours.

Step 3: Configuring LUCCA

This operation must be performed by an administrator.

Once the configuration has been completed in your Google management interface, you need to return to Lucca's authentication settings to integrate the metadata URL or, if applicable, the IdP file downloaded in step 2.

By default, the standard signature and encryption parameters are activated. These parameters can be modified if you have a specific configuration.

Once this information has been entered and saved, you can activate the SSO connection as soon as you are ready:

Once the login via SSO has been activated, you can deactivate the ability for employees to access the Lucca login page which allows your employees to log in with their Lucca login and a personalized password, by deactivating the "Lucca login/password login".
