- Automatically try to fall back to using StartTLS when using TLS
doesn't work. Only complain when both don't work.
- Remember (in-memory) which one worked and keeping using that one
in the future (unless the pod restarts).
- This enhances our LDAP client code to make it possible to optionally
dial an LDAP server without TLS and then use StartTLS to upgrade
the connection to TLS.
- The controller for LDAPIdentityProviders is not using this option
yet. That will come in a future commit.
Previously, our controllers would automatically create a CredentialIssuer with a singleton name. The helpers we had for this also used "raw" client access and did not take advantage of the informer cache pattern.
With this change, the CredentialIssuer is always created at install time in the ytt YAML. The controllers now only update the existing CredentialIssuer status, and they do so using the informer cache as much as possible.
This change is targeted at only the kubecertagent controller to start. The impersonatorconfig controller will be updated in a following PR along with other changes.

Reflect the upstream group membership into the Supervisor's
downstream tokens, so they can be added to the user's
identity on the workload clusters.
LDAP group search is configurable on the
LDAPIdentityProvider resource.
See RFC6648 which asks that people stop using `X-` on header names.
Also Matt preferred not mentioning "IDP" in the header name.

This change makes it easier to understand misconfigurations caused
by issuers with extraneous trailing slashes.

to avoid garbage collection breaking the refresh flow
Also changed the access token lifetime to be 2 minutes instead of 15
since we now have cert caching.
The supervisor treats all events the same hence it must use a
singleton queue.
Updated the integration test to remove the data race caused by
calling methods on testing.T outside of the main test go routine.

Followup on the previous comment to split apart the ServiceAccount of the kube-cert-agent and the main concierge pod. This is a bit cleaner and ensures that in testing our main Concierge pod never requires any privileged permissions.

Since 0dfb3e95c5, we no longer directly create the kube-cert-agent Pod, so our "use"
permission on PodSecurityPolicies no longer has the intended effect. Since the deployments controller is now the
one creating pods for us, we need to get the permission on the PodSpec of the target pod instead, which we do somewhat
simply by using the same service account as the main Concierge pods.
We still set `automountServiceAccountToken: false`, so this should not actually give any useful permissions to the
agent pod when running.

This change updates the impersonator logic to pass through requests
that authenticated via a bearer token that asserts a UID. This
allows us to support service account tokens (as well as any other
form of token based authentication).

This controller is responsible for cleaning up kube-cert-agent pods that were deployed by previous versions.
They are easily identified because they use a different `kube-cert-agent.pinniped.dev` label compared to the new agent pods (`true` vs. `v2`).

This is a relatively large rewrite of much of the kube-cert-agent controllers. Instead of managing raw Pod objects, they now create a single Deployment and let the builtin k8s controller handle it from there.
This reduces the amount of code we need and should handle a number of edge cases better, especially those where a Pod becomes "wedged" and needs to be recreated.

- Make PINNIPED_TEST_LDAP_LDAPS_CA_BUNDLE optional for integration tests
- When there is no CA bundle provided, be careful to use nil instead of
an empty bundle, because nil means to use the OS defaults
Now that we have the fix from https://github.com/kubernetes/kubernetes/pull/97693, we no longer need these sleeps.
The underlying authenticator initialization is still asynchronous, but should happen within a few milliseconds.
