- Add `AllowPasswordGrant` boolean field to OIDCIdentityProvider's spec
- The oidc upstream watcher controller copies the value of
`AllowPasswordGrant` into the configuration of the cached provider
- Add password grant to the UpstreamOIDCIdentityProviderI interface
which is implemented by the cached provider instance for use in the
authorization endpoint
- Enhance the IDP discovery endpoint to return the supported "flows"
for each IDP ("cli_password" and/or "browser_authcode")
- Enhance `pinniped get kubeconfig` to help the user choose the desired
flow for the selected IDP, and to write the flow into the resulting
kubeconfg
- Enhance `pinniped login oidc` to have a flow flag to tell it which
client-side flow it should use for auth (CLI-based or browser-based)
- In the Dex config, allow the resource owner password grant, which Dex
implements to also return ID tokens, for use in integration tests
- Enhance the authorize endpoint to perform password grant when
requested by the incoming headers. This commit does not include unit
tests for the enhancements to the authorize endpoint, which will come
in the next commit
- Extract some shared helpers from the callback endpoint to share the
code with the authorize endpoint
- Add new integration tests
This is a new pacakge internal/oidc/provider/formposthtml containing a number of static files embedded using the relatively recent Go "//go:embed" functionality introduced in Go 1.16 (https://blog.golang.org/go1.16).
The Javascript and CSS files are minifiied and injected to make a single self-contained HTML response. There is a special Content-Security-Policy helper to calculate hash-based script-src and style-src rules.
This new code is covered by a new integration test that exercises the JS/HTML functionality in a real browser outside of the rest of the Supervisor.

This is a bit more clear. We're changing this now because it is a non-backwards-compatible change that we can make now since none of this RFC8693 token exchange stuff has been released yet.
There is also a small typo fix in some flag usages (s/RF8693/RFC8693/)

This refactors the `UpstreamOIDCIdentityProviderI` interface and its implementations to pass ID token claims through a `*oidctypes.Token` return parameter rather than as a third return parameter.

We missed this in the original interface specification, but the `grant_type=authorization_code` requires it, per RFC6749 (https://tools.ietf.org/html/rfc6749#section-4.1.3).

Also use ConstantTimeCompare() to compare CSRF tokens to prevent
leaking any information in how quickly we reject bad tokens.

Also aggresively refactor for readability:
- Make helper validations functions for each type of storage
- Try to label symbols based on their downstream/upstream use and group them
accordingly

- Also handle several more error cases
- Move RequireTimeInDelta to shared testutils package so other tests
can also use it
- Move all of the oidc test helpers into a new oidc/oidctestutils
package to break a circular import dependency. The shared testutil
package can't depend on any of our other packages or else we
end up with circular dependencies.
- Lots more assertions about what was stored at the end of the
request to build confidence that we are going to pass all of the
right settings over to the token endpoint through the storage, and
also to avoid accidental regressions in that area in the future

Also refactor to get rid of duplicate test structs.
Also also don't default groups ID token claim because there is no standard one.
Also also also add some logging that will hopefully help us in debugging in the
future.

Because we want it to implement an AuthcodeExchanger interface and
do it in a way that will be more unit test-friendly than the underlying
library that we intend to use inside its implementation.
