Configure SAML SSO

Single Sign-On (or SSO) allows you to manage your organization’s entire membership via a third-party provider.

GitGuardian supports the SAML2 standard for SSO which allows the Owner or any Manager, of the workspace to configure any SAML2-enabled Identity Provider (IdP) system (Google, Okta,...).

Set up SSO​

To configure your SSO, navigate to Settings > Authentication.

Detailed set up procedures are available for the following IdP:

For all other SAML2-enabled IdP, you can follow the generic procedure.

Just-In-Time (JIT) provisioning​

GitGuardian supports Just-In-Time (JIT) provisioning. New members of your workspace are automatically registered with GitGuardian on their first login attempt with SAML2 SSO if they are authorized on the IdP side.

You don't need to invite users manually. You just need to authorize them on the IdP's side by being part of the "GitGuardian group". Users who are not part of the GitGuardian group on the IdP side will be rejected during their attempt to sign in via SSO.

info

GitGuardian does not support JIT deprovisioning yet but you can use the SCIM to automatically deprovision your users.

Default access level​

Because GitGuardian uses Just-In-Time (JIT) provisioning, new members will be given a default access level upon their first login.

"Member" is the default setting. You can modify this default in your Authentication settings page.

SSO default access level

If you selected "Member" as the default access level and your workspace is under the Business plan, you must also configure whether new Members will be part of the "All-incidents" team or not upon sign up. This option is available in Business plan.

SSO All-incidents team default membership setting

Force SSO​

Once you have successfully set up an SAML2 SSO integration, in your Authentication settings page, you have the option to force the SSO:

  • If the option is turned ON, all the members of your workspace will have to go through your IdP in order to be able to access your GitGuardian workspace. Thus, only the users you have authorized on your IdP’s side will be able to sign into your GitGuardian workspace. If you want to activate the option, you will have the possibility to visualize the users that may encounter an issue.
  • If the option is turned OFF, members of your workspace can still login via SSO, going through your IdP, but they can also sign up via email. As a result, users that are not whitelisted on the IdP side can still login to your GitGuardian workspace.

SSO force sso

Once SSO is forced, all the members of the workspace, including the owner, will have to connect using SSO. If the owner has never connected with SSO, you will not be able to activate the option.

Make sure that your SSO connection works before enforcing SSO. In case of issues, you can contact the support team for assistance.

Set up procedures​

  10. Finalize your setup by testing the SSO authentication using the Login URL provided in the GitGuardian dashboard SAML configuration page.

Generic procedure for SAML2-enabled IdP​

1. Register GitGuardian on your Identity provider.​

In order to integrate GitGuardian with your Identity Provider, you must first register GitGuardian (Service Provider) as an application on the IdP’s side. Follow these steps carefully:

  1. Navigate to Settings > Authentication
  2. Click on "Configure"

SSO Service provider info configure

  1. On your IdP:
    1. Fill in the SAML endpoint provided by GitGuardian (ACS url, SP Entity id)
    2. Fill in Email or EmailAddress as the primary identifier (Name ID format).
      Refer to our FAQ if this Name ID format is not available in your IdP.
    3. Set RSA_SHA256 for the signature algorithm, and SHA256 for the digest algorithm for your response.
      Some Identity Providers (IdPs) may require you to sign either the response message or the response assertions. GitGuardian provides the ability to specify this IdP behavior.
      Note that at least one of these, either the response message or the response assertions, must be signed.
    4. Configure first_name and last_name mapped attributes.

SSO Service provider info

2. Register your IdP on GitGuardian’s side​

Once GitGuardian is registered as an application on your IdP’s side, you need to provide your IdP metadata fields on GitGuardian (Service Provider side) in order to complete the integration:

  1. While still on the Authentication config page of your workspace settings, complete the form with:
    • Entity Id [required]
    • Single Sign On Url [required]
    • Single Log Out Url [optional]
    • X509 certificate [required]
  2. Submit the form to fully register the SAML integration. SSO IdP info
  3. The setup is complete. Your workspace will have a dedicated SSO login url for your collaborators to sign in using your IdP. SSO login url

You can register this SSO login url on the IdP side to enable the SSO flow with one click directly in the IdP interface. However this IdP-Initiated flow carries a security risk and is therefore NOT recommended. Make sure you understand the risks before enabling IdP-initiated SSO.

FAQ​

How to verify that my SSO connection is working?

If you have not reserved an email domain, please remember your SSO login URL.

  1. Make sure to know your login credentials, i.e., your email and password.
  2. Log out of the application.
  3. Go to the SSO login URL, and log in by selecting the SSO option.
    For additional security purpose, GitGuardian will ask you to submit your email and password to confirm your identity.

My Identity Provider (IdP) does not support "emailAddress" as the Name ID format. What do I do?

If your IdP does not support emailAddress as the Name ID format, please contact us. We will allow you to use unspecified as the Name ID format.

caution

When using unspecified as the Name ID format, you must ensure that you send the email addresses of your IdP users as an email_address attribute. This is mandatory, as email is the unique identifier that GitGuardian uses for its users.

SSO NameId unspecified and email_address attribute

I want to configure MFA for GitGuardian. What do I do?

Combining SSO with MFA is more secure than using a simple SSO connection.

Leverage the MFA feature provided by all the SSO providers we support. We strongly advise that you enable the Force SSO setting to ensure that through SSO authentication, MFA is applied to all users authenticating to GitGuardian.
