GLPI samlSSO plugin configuration​

info

By default, GLPI only offers OAuth authentication to subscribers. This guide describes how to integrate authentik with GLPI via SAML using the community plugin named samlSO.

Install the samlSSO plugin​

  1. Download latest release from the samlSSO GitHub project.
  2. Unpack the release ZIP file into the glpi/data/marketplace directory of your GLPI installation.
  3. Log in to GLPI as an administrator and navigate to Setup > Plugins.
  4. Click the Install icon (folder with a + symbol) next to the samlSSO plugin.
  5. In the pop-up window that opens, click Enable.

Add a samlSSO instance​

  1. Navigate to Setup > samlSSO.

  2. Click the Add button and configure the following required settings:

    • On the General tab:
      • Friendly name: authentik
      • Is active: toggled on
    • On the Security tab:
      • Strict: toggled on
      • JIT user creation: toggled on

  3. Open the Service Provider tab and take note of the AcsUrl and sloURL. These values will be required in the next section.

  4. Click Save.

authentik configuration​

To support the integration of GLPI with authentik, you need to create an application/provider pair in authentik.

Create an application and provider in authentik​

  1. Log in to authentik as an administrator and open the authentik Admin interface.

  2. Navigate to Applications > Applications and click Create with Provider to create an application and provider pair. (Alternatively you can first create a provider separately, then create the application and connect it with the provider.)

    • Application: provide a descriptive name, an optional group for the type of application, the policy engine mode, and optional UI settings. Take note of the Slug value as it will be required later.
    • Choose a Provider type: select SAML Provider as the provider type.
    • Configure the Provider: provide a name (or accept the auto-provided name), the authorization flow to use for this provider, and the following required configurations.
      • Set the ACS URL to the AcsURL value from GLPI.
      • Set the Service Provider Binding to Post.
      • Set the SLS URL to the sloURL value from GLPI.
      • Under Advanced protocol settings:
        • Select any available Signing Certificate and enable Sign assertions.
        • Set NameID Property Mapping to authentik default SAML Mapping: Email.
    • Configure Bindings (optional): you can create a binding (policy, group, or user) to manage the listing and access to applications on a user's My applications page.

  3. Click Submit to save the new application and provider.

Download certificate file​

  1. Log in to authentik as an administrator and open the authentik Admin interface.
  2. Navigate to Applications > Providers and click on the name of the provider that you created in the previous section.
  3. Under Related objects > Download signing certificate, click on Download. This downloaded file is your certificate file and it will be required in the next section.

GLPI configuration​

  1. Log in to GLPI as an administrator and navigate to Setup > samlSSO.

  2. Click on the authentik samlSSO instance and configure the following settings:

    • On the Identity Provider tab:
      • Set the Entity ID to authentik
      • Set the SSO URL to https://authentik.company/application/saml/<application_slug>/sso/binding/redirect/.
      • Set the SLO URL to https://authentik.company/application/saml/<application_slug>/slo/binding/redirect/.
      • Set X509 certificate to the contents of the certificate file that you downloaded from authentik.

  3. Click Save to apply the changes.

JIT rules (optional)​

It's possible to auto assign profiles and groups when a user is created in GLPI.

  1. Log in to GLPI as an administrator, navigate to Setup > samlSSO > JIT import rules, and click Add.
  2. Provide a Name, Logical operator type, set Active to Yes, and then click Add.
  3. Configure the following settings:
    • On the Criteria tab, create a criterion to match users.
    • On the Actions tab, create actions to apply to matched users.
      • You may want to add recursive=yes as an action, so that matched users have access to all entities.
  4. Once finished, return to the Rule tab and click Save.

Configuration verification​

To confirm that authentik is properly configured with GLPI, log out and click the new authentik login button on the right side. You should be redirected to authentik and once authenticated, you will be signed in to GLPI.
