2. Configuring Rancher for Microsoft AD FS

After you complete Configuring Microsoft AD FS for Rancher, enter your AD FS information into Rancher to allow AD FS users to authenticate with Rancher.

Important Notes For Configuring Your ADFS Server:
  • The SAML 2.0 WebSSO Protocol Service URL is: https://<RANCHER_SERVER>/v1-saml/adfs/saml/acs
  • The Relying Party Trust identifier URL is: https://<RANCHER_SERVER>/v1-saml/adfs/saml/metadata
  • You must export the federationmetadata.xml file from your AD FS server. This can be found at: https://<AD_SERVER>/federationmetadata/2007-06/federationmetadata.xml
  1. In the top left corner, click ☰ > Users & Authentication.

  2. In the left navigation menu, click Auth Provider.

  3. Click ADFS.

  4. Complete the Configure AD FS Account form. Microsoft AD FS lets you specify an existing Active Directory (AD) server. The configuration section below describe how you can map AD attributes to fields within Rancher.

  5. After you complete the Configure AD FS Account form, click Enable.

    Rancher redirects you to the AD FS login page. Enter credentials that authenticate with Microsoft AD FS to validate your Rancher AD FS configuration.

    note

    You may have to disable your popup blocker to see the AD FS login page.

Result: Rancher is configured to work with MS FS. Your users can now sign into Rancher using their MS FS logins.
