Integrate GitLab with Zero Trust Network Access

In this topic, you will find general instructions on how to integrate GitLab with Portnox™ Zero Trust Network Access.

Create a Portnox Cloud application configuration

In this step, you will create a configuration in Portnox Cloud that will contain all the information necessary to integrate with GitLab.

  1. In a new tab of your browser, open your Portnox Cloud account by accessing the following URL: https://clear.portnox.com/

    From now on, we will call this tab the Portnox tab.

  2. In the Cloud portal top menu, click on the Zero Trust Resources option.

  3. On the Resources screen, click on the Create resource button.

    1. In the What type of resource is this? section, select the SSO web application option.
    2. In the Authentication protocol section, select the SAML option.
    3. Click on the Next button.

  4. Optional: If you have more than one SAML identity provider configured, select the identity provider in the Select an identity provider to use for this resource section.
  5. In the Resource details section, enter a Resource name and optionally a Description.

    In this example, we used the name GitLab for the new application configuration but you can use any name you like.

  6. Keep this browser tab open. You will need it later.

Open your GitLab SAML SSO settings

In this section, you will access your GitLab administrative interface and find the SAML single sign-on (SSO) settings.

  1. In another tab of your browser, open GitLab by accessing the following URL: https://gitlab.com/. Then, log in to your account.

    From now on, we will call this tab the GitLab tab.

  2. Go to the SAML SSO settings for the group that you administer.

    You can access your group’s SAML SSO settings in two ways:

    • Click: your profile picture > your name > Groups > your group, and from the left-hand menu, select the Settings > SAML SSO option.

    • Go to the following URL: https://gitlab.com/groups/<your_group>/-/saml, replacing <your_group> with the identifier of your group.

Copy configuration values from the Portnox tab to the GitLab tab

In this section, you will copy the values displayed by Portnox Cloud and paste them in the relevant fields in the GitLab SAML SSO setup section.

    1. Click on the Save changes button.

Result: You have configured GitLab to be accessible using Portnox Zero Trust Network Access.

Note:
Single sign-on with Zero Trust Network Access will not be enforced for your personal account. It will be activated when you or your group members access the group. You can share the group’s single sign-on URL with your group members. This URL is specified in the GitLab single sign-on URL field, and has the following format: https://gitlab.com/groups/your_group/-/saml/sso?token=token_value.
