Integrate with DokuWiki DokuWiki community

What is DokuWiki

DokuWiki is an open source wiki application licensed under GPLv2 and written in the PHP programming language. It works on plain text files and thus does not need a database. Its syntax is similar to the one used by MediaWiki and it is often recommended as a more lightweight, easier to customize alternative to MediaWiki.

Preparation

The following placeholders are used in this guide:

  • dokuwiki.company is the FQDN of the DokiWiki installation.
  • authentik.company is the FQDN of the authentik installation.

:::note 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 DocuWiki 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.
  • Choose a Provider type: select OAuth2/OpenID Connect 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.
    • Note the Client ID and Client Secret values because they will be required later.
    • Set a Strict redirect URI to https://docuwiki.company/doku.php.
    • Select any available signing key.
    • Under Advanced Protocol Settings, add the following OAuth mapping under Scopes: authentik default OAuth Mapping: OpenID 'offline_access'
  • 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.
  1. Click Submit to save the new application and provider.

DokuWiki configuration

From the Administration interface of your DocuWiki installation, navigate to Extension Manager and install the following extensions:

Then, under the Configuration Settings section, update the oauth and oauthgeneric options:

For oauth: - Select the following option: plugin»oauth»register-on-auth

:::warning When using preferred_username as the user identifier, ensure that the Allow users to change username setting is disabled to prevent authentication issues. You can configure DocuWiki to use either the sub or preferred_username as the UID field under plugin»oauthgeneric»json-user. The sub option uses a unique, stable identifier for the user, while preferred_username uses the username configured in authentik. :::

For oauthgeneric:

  • Set plugin»oauthgeneric»key to the Client ID from authentik
  • Set plugin»oauthgeneric»secret to the Client Secret from authentik
  • Set plugin»oauthgeneric»authurl to https://authentik.company/application/o/authorize/
  • Set plugin»oauthgeneric»tokenurl to https://authentik.company/application/o/token/
  • Set plugin»oauthgeneric»userurl to https://authentik.company/application/o/userinfo/
  • Set plugin»oauthgeneric»authmethod to Bearer Header
  • Set plugin»oauthgeneric»scopes to email, openid, profile, offline_access
  • Select plugin»oauthgeneric»needs-state
  • Set plugin»oauthgeneric»json-user to preferred_username
  • Set plugin»oauthgeneric»json-name to name
  • Set plugin»oauthgeneric»json-mail to email
  • Set plugin»oauthgeneric»json-grps togroups

Once that is done, navigate to the Authentication sub-section of the Administration interface's Configuration Settings section and enable oauth under Authentication backend.

Configuration verification

To verify that authentik is correctly configured with DocuWiki, log out and log back in through authentik. You should notice a new button on the login page.
