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.

This change updates the impersonator logic to use the delegated
authorizer for all non-rest verbs such as impersonate. This allows
it to correctly perform authorization checks for incoming requests
that set impersonation headers while not performing unnecessary
checks that are already handled by KAS.
The audit layer is enabled to track the original user who made the
request. This information is then included in a reserved extra
field original-user-info.impersonation-proxy.concierge.pinniped.dev
as a JSON blob.

$PINNIPED_TEST_SUPERVISOR_UPSTREAM_OIDC_ISSUER_CA_BUNDLE was recently
changed to be a base64 encoded value, so this script does not need to
base64 encode the value itself anymore.
- Also some light prefactoring in login.go to make room for LDAP-style
login, which is not implemented yet in this commit. TODOs are added.
- And fix a test pollution problem in login_oidc_test.go where it was
using a real on-disk CLI cache file, so the tests were polluted by
the contents of that file and would sometimes cause each other to
fail.
Also force the LDAP server pod to restart whenever the LDIF file
changes, so whenever you redeploy the tools deployment with a new test
user password the server will be updated.
Unfortunately, Secrets do not seem to have a Generation field, so we
use the ResourceVersion field instead. This means that any change to
the Secret will cause us to retry the connection to the LDAP server,
even if the username and password fields in the Secret were not
changed. Seems like an okay trade-off for this early draft of the
controller compared to a more complex implementation.
This early version of the controller is not intended to act as an
ongoing health check for your upstream LDAP server. It will connect
to the LDAP server to essentially "lint" your configuration once.
It will do it again only when you change your configuration. To account
for transient errors, it will keep trying to connect to the server
until it succeeds once.
This commit does not include looking for changes in the associated bind
user username/password Secret.
Avoid them because they can't be used in GoLand for running integration
tests in the UI, like running in the debugger.
Also adds optional PINNIPED_TEST_TOOLS_NAMESPACE because we need it
on the LDAP feature branch where we are developing the upcoming LDAP
support for the Supervisor.
- Bad usernames and passwords aren't really errors, since they are
based on end-user input.
- Other kinds of authentication failures are caused by bad configuration
so still treat those as errors.
- Empty usernames and passwords are already prevented by our endpoint
handler, but just to be safe make sure they cause errors inside the
authenticator too.
- The unit tests for upstreamldap.Provider need to mock the LDAP server,
so add an integration test which allows us to get fast feedback for
this code against a real LDAP server.
- Automatically wrap the user search filter in parenthesis if it is not
already wrapped in parens.
- More special handling for using "dn" as the username or UID attribute
name.
- Also added some more comments to types_ldapidentityprovider.go.tmpl
