info

This documentation lists only the settings that you need to change from their default values. Be aware that any changes other than those explicitly mentioned in this guide could cause issues accessing your application.

authentik configuration​

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

Create an application and provider​

SAML provider changes in authentik 2026.5

authentik 2026.5 introduces changes to how the SAML provider behaves. Specifically, the provider now automatically sets the Issuer value to: https://authentik.company/application/saml/<application_slug>/metadata/

Older versions of authentik set this value to authentik by default. If you're running an older version, please set Issuer to https://authentik.company/application/saml/<application_slug>/metadata/, where <application_slug> is the slug that you selected for the application.

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

  2. Navigate to Applications > Applications and click New Application to open the application wizard.

    • 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 https://accounts.webex.placetel.de/users/saml/auth.
      • Set the SLS URL to https://accounts.webex.placetel.de/users/saml/idp_sign_out.
      • Under Advanced protocol settings, set an available Signing Certificate and ensure that Sign assertions and Sign responses are enabled.
      • Remove all Property Mappings except for authentik default SAML Mapping: Email.
      • 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 Application Dashboard page.

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

Download the metadata 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 > Metadata, click Download. This downloaded file is your SAML Metadata file and is required in the next section.

Placetel configuration​

To integrate Placetel with authentik, configure SSO in the Placetel portal.

  1. Log in to the Placetel portal as an Administrator.
  2. Click the organization name in the bottom-left corner and select Settings.
  3. Scroll to the bottom of the page. Next to the Single Sign On (SSO/SAML) section heading, select Edit.
  4. In the Import section, click Choose File and upload the SAML Metadata file that you downloaded from authentik.
  5. In the Settings section, confirm or enter the following values:
    • SP Entity ID: https://web.placetel.de with no trailing slash.
    • IDP Entity ID: https://authentik.company/application/saml/<application_slug>/metadata/
    • Domains: company.tld. Add any other email domains that should use SSO.
  6. Leave Activate Single Sign On unchecked until you are ready to switch Placetel sign-ins to SSO.
  7. Click Save settings.

Activate SSO​

After saving the configuration, return to the Placetel SSO configuration page, check Activate Single Sign On, and click Save settings.

Configuration verification​

To confirm that authentik is properly configured with Placetel, open the Placetel portal and sign in with an existing Placetel user's email address. Placetel does not create new users through authentik. After clicking Login, you should be redirected to authentik and then signed in to Placetel.

Login link

The default login link on the Placetel homepage will not work.
