Shibboleth

Allows users to authenticate using their Shibboleth credentials by configuring Shibboleth as a federated identity provider via SAML.

Preparation​

The following placeholders are used in this guide:

  • authentik.company is the FQDN of the authentik installation.
  • shibboleth.company is the FQDN of the Shibboleth IdP installation.
  • shibboleth-slug is the slug you will assign to the SAML source in authentik (e.g., shibboleth).

authentik configuration​

To integrate Shibboleth with authentik you will need to create a SAML source in authentik.

Create a SAML source in authentik​

  1. Log in to authentik as an administrator and open the authentik Admin interface.
  2. Navigate to Directory > Federation and Social login and click Create.
  3. Select SAML Source and configure the following settings:
    • Set Name to Shibboleth.
    • Set Slug to shibboleth (this sets the slug used in Shibboleth's metadata url).
    • Set SSO URL to https://shibboleth.company/idp/profile/SAML2/Redirect/SSO.
    • Set Binding Type to Redirect.
    • Set Issuer to https://authentik.company/source/saml/<shibboleth-slug>/metadata/.
    • Set NameID Policy to Transient.
      NameID Policy

      Shibboleth supports the Transient NameID by default. You will need to reconfigure Shibboleth to use other NameIDs.

    • Set Signing Keypair to an authentik certificate (e.g., the default authentik Self-signed Certificate).
    • Set Encryption Certificate to an authentik certificate (e.g., the default authentik Self-signed Certificate).
  4. Click Finish.
Display new source on login screen

For instructions on how to display the new source on the authentik login page, refer to the Add sources to default login page documentation.

Embed new source in flow Enterprise

For instructions on embedding the new source within a flow, such as an authorization flow, refer to the Source Stage documentation.

Shibboleth configuration​

To integrate Shibboleth with authentik you will need to add authentik as a service provider in your Shibboleth IdP.

Add authentik as a Service Provider​

  1. Edit /opt/shibboleth-idp/conf/metadata-providers.xml on the Shibboleth IdP server.
  2. Add the following MetadataProvider element before the final closing tag of the existing MetadataProvider block:
<MetadataProvider id="Authentik"
                  xsi:type="FileBackedHTTPMetadataProvider"
                  backingFile="%{idp.home}/metadata/authentik-metadata.xml"
                  metadataURL="https://authentik.company/source/saml/<shibboleth-slug>/metadata/" />
  1. Restart the Shibboleth IdP to apply the changes.
