Overview

The proxy outpost sets the following user-specific headers:

  • X-authentik-username: akadmin

    The username of the currently logged in user

  • X-authentik-groups: foo|bar|baz

    The groups the user is member of, separated by a pipe

  • X-authentik-email: root@localhost

    The email address of the currently logged in user

  • X-authentik-name: authentik Default Admin

    Full name of the current user

  • X-authentik-uid: 900347b8a29876b45ca6f75722635ecfedf0e931c6022e3a29a8aa13fb5516fb

    The hashed identifier of the currently logged in user.

Additionally, you can set additionalHeaders attribute on groups or users to set additional headers:

additionalHeaders:
    X-test-header: test-value

Besides these user-specific headers, some application specific headers are also set:

  • X-authentik-meta-outpost: authentik Embedded Outpost

    The authentik outpost's name.

  • X-authentik-meta-provider: test

    The authentik provider's name.

  • X-authentik-meta-app: test

    The authentik application's slug.

  • X-authentik-meta-version: goauthentik.io/outpost/1.2.3

    The authentik outpost's version.

Only in proxy mode​

  • X-Forwarded-Host:

    The original Host header sent by the client. This is set as the Host header is set to the host of the configured backend.

HTTPS​

The outpost listens on both 9000 for HTTP and 9443 for HTTPS.

info

If your upstream host is HTTPS, and you're not using forward auth, you need to access the outpost over HTTPS too.

Logging out​

Login is done automatically when you visit the domain without a valid cookie.

When using single-application mode, navigate to app.domain.tld/outpost.goauthentik.io/sign_out.

When using domain-level mode, navigate to auth.domain.tld/outpost.goauthentik.io/sign_out, where auth.domain.tld is the external host configured for the provider.

To log out, navigate to /outpost.goauthentik.io/sign_out.

Allowing unauthenticated requests​

To allow un-authenticated requests to certain paths/URLs, you can use the Unauthenticated URLs / Unauthenticated Paths field.

Each new line is interpreted as a regular expression, and is compiled and checked using the standard Golang regex parser.

The behaviour of this field changes depending on which mode you're in.

Proxy and Forward auth (single application)​

In this mode, the regular expressions are matched against the Request's Path.

Forward auth (domain level)​

In this mode, the regular expressions are matched against the Request's full URL.

Dynamic backend selection​

You can configure the backend the proxy should access dynamically via Scope mappings. To do so, create a new Scope mapping, with a name and scope of your choice. As expression, use this:

return {
    "ak_proxy": {
        "backend_override": f"http://foo.bar.baz/{request.user.username}"
    }
}

Afterwards, edit the Proxy provider and add this new mapping. The expression is only evaluated when the user logs into the application.
