authentik configuration

Redirect URI changes in authentik 2026.5

In authentik versions earlier than 2026.5, all Redirect URIs are automatically treated as Authorization type. If you are using one of these older authentik versions, add only the Authorization URL to your Redirect URIs and do not configure a Post Logout URI.

To support the integration of OpenProject with authentik, you need to create a property mapping and an application/provider pair in authentik.

Create a scope mapping

OpenProject requires a first and last name for each user. By default, authentik only stores a user's full name as a single string. Therefore you need to create a property mapping to provide separate first and last names to OpenProject.

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

2. Navigate to Customization > Property Mappings and click Create.

   • Select type: select Scope Mapping as the property mapping type.

   • Configure the Scope Mapping: provide a descriptive name (e.g. OpenProject Profile Scope), and an optional description.

     • Scope name: profile
     • Expression:

     name = request.user.name or request.user.username
     first_name, _, last_name = name.rpartition(" ")
     
     return {
         "name": name,
         "given_name": first_name or name,
         "family_name": last_name or name,
         "preferred_username": request.user.username,
         "nickname": request.user.username,
         "groups": [group.name for group in request.user.groups.all()],
         "first_name": first_name or name,
         "last_name": last_name or name,
     }

3. Click Finish to save the property mapping.

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 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. Note the application Slug because it will be required later.
   • Choose a Provider type: select OAuth2/OpenID 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.
     • Protocol settings:
       • Note the Client ID and Client Secret values because they will be required later.
       • Redirect URI:
         • Strict Authorization: https://openproject.company/auth/oidc-authentik/callback
       • Signing Key: select any available signing key.
     • Advanced protocol settings:
       • Scopes:
         • Remove authentik default OAuth Mapping: OpenID 'profile' from Selected Scopes.
         • Add the scope that you created in the previous section (e.g. OpenProject Profile Scope) to Selected Scopes.
   • 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.

OpenProject configuration

To support the integration of authentik with OpenProject, you need to configure authentication in the OpenProject administration interface.

1. Log in to OpenProject as an administrator, click your profile icon in the top-right corner, and then click Administration.
2. Navigate to Authentication > OpenID providers.
3. Click + OpenID provider and select Custom.
4. Set Display Name to authentik to match the /auth/oidc-authentik/callback redirect URI configured in authentik.
5. In the discovery endpoint section, select I have a discovery endpoint URL, and enter: https://authentik.company/application/o/<application_slug>/.well-known/openid-configuration
6. Continue to Advanced configuration > Metadata. The values should be automatically populated based on your discovery endpoint URL. If not, copy these values from the Overview page of the OpenProject provider in authentik.
7. Under Advanced configuration > Client details, enter the Client ID and Client Secret values from authentik.
8. Under Optional configuration > Attribute mapping, enter the following required configurations:
   • Mapping for: Username: preferred_username
   • Mapping for: Email: email
   • Mapping for: First Name: first_name
   • Mapping for: Last Name: last_name
9. Click Finish setup.

OpenProject can optionally synchronize groups from the groups claim included in the scope mapping above. Enable Synchronize groups only if authentik should become responsible for OpenProject group assignments for users who log in with this provider. When enabled, OpenProject removes group memberships that are not included in the claim on each login.

Configuration verification

To confirm that authentik is properly configured with OpenProject, log out of OpenProject, and then click on authentik and enter your authentik credentials to log back in.
