Deprovision Windows Active Directory Authentication

You can remove Windows Active Directory authentication from StarlingX.

Procedure

1. Remove the configuration of kube-apiserver to use oidc-auth-apps for authentication.

   1. Determine the UUIDs of parameters used in the kubernetes kube-apiserver group.

      These include oidc_client_id, oidc_groups_claim, oidc_issuer_url and oidc_username_claim.

      ~(keystone_admin)]$ system service-parameter-list
      

   2. Delete each parameter.

      ~(keystone_admin)]$ system service-parameter-delete <UUID>
      

   3. Apply the changes.

      ~(keystone_admin)]$ system service-parameter-apply kubernetes
      

2. Uninstall oidc-auth-apps.

   ~(keystone_admin)]$ system application-remove oidc-auth-apps
   

3. Clear the helm-override configuration.

   ~(keystone_admin)]$ system helm-override-update oidc-auth-apps dex kube-system --reset-values
   ~(keystone_admin)]$ system helm-override-show oidc-auth-apps dex kube-system
   
   ~(keystone_admin)]$ system helm-override-update oidc-auth-apps oidc-client kube-system --reset-values
   ~(keystone_admin)]$ system helm-override-show oidc-auth-apps oidc-client kube-system
   

4. Remove secrets that contain certificate data.

   ~(keystone_admin)]$ kubectl delete secret local-dex.tls -n kube-system
   ~(keystone_admin)]$ kubectl delete secret dex-client-secret -n kube-system
   ~(keystone_admin)]$ kubectl delete secret wadcert -n kube-system
   

5. Remove any RBAC RoleBindings added for OIDC users and/or groups.

   For example:

   $ kubectl delete clusterrolebinding testuser-rolebinding
   $ kubectl delete clusterrolebinding billingdeptgroup-rolebinding
