Proof-of-concept implementation of a potential new Supervisor feature
which allows arbitrary upstream ID token claims to be mapped into a
new top-level claim in the ID tokens issued by the Supervisor.
- Change update-codegen.sh script to also generated openapi code for the
aggregated API types
- Update both aggregated API servers' configuration to make them serve
the openapi docs for the aggregated APIs
- Add new integration test which runs `kubectl explain` for all Pinniped
API resources, and all fields and subfields of those resources
- Update some the comments on the API structs
- Change some names of the tmpl files to make the filename better match
the struct names
- For backwards compatibility with older Pinniped CLIs, the pinniped-cli
client does not need to request the username or groups scopes for them
to be granted. For dynamic clients, the usual OAuth2 rules apply:
the client must be allowed to request the scopes according to its
configuration, and the client must actually request the scopes in the
authorization request.
- If the username scope was not granted, then there will be no username
in the ID token, and the cluster-scoped token exchange will fail since
there would be no username in the resulting cluster-scoped ID token.
- The OIDC well-known discovery endpoint lists the username and groups
scopes in the scopes_supported list, and lists the username and groups
claims in the claims_supported list.
- Add username and groups scopes to the default list of scopes
put into kubeconfig files by "pinniped get kubeconfig" CLI command,
and the default list of scopes used by "pinniped login oidc" when
no list of scopes is specified in the kubeconfig file
- The warning header about group memberships changing during upstream
refresh will only be sent to the pinniped-cli client, since it is
only intended for kubectl and it could leak the username to the
client (which may not have the username scope granted) through the
warning message text.
- Add the user's username to the session storage as a new field, so that
during upstream refresh we can compare the original username from the
initial authorization to the refreshed username, even in the case when
the username scope was not granted (and therefore the username is not
stored in the ID token claims of the session storage)
- Bump the Supervisor session storage format version from 2 to 3
due to the username field being added to the session struct
- Extract commonly used string constants related to OIDC flows to api
package.
- Change some import names to make them consistent:
- Always import github.com/coreos/go-oidc/v3/oidc as "coreosoidc"
- Always import go.pinniped.dev/generated/latest/apis/supervisor/oidc
as "oidcapi"
- Always import go.pinniped.dev/internal/oidc as "oidc"
The following validation is enforced:
1. Names must start with client.oauth.pinniped.dev-
2. Redirect URIs must start with https://
or http://127.0.0.1
or http://::1
3. All spec lists must not have duplicates
Added an integration test to assert all static validations.

Also:
- Make our code generator script work with Go 1.17
- Make our update.sh script work on linux
- Update the patch versions of the old Kube versions that we were using
to generate code (see kube-versions.txt)
- Use our container images from ghcr instead of
projects.registry.vmware.com for codegen purposes
- Make it easier to debug in the future by passing "-v" to the Kube
codegen scripts
- Updated copyright years to make commit checks pass
- Change list of attributeParsingOverrides to a map
- Add unit test for sAMAccountName as group name without the override
- Change some comments in the the type definition.
- 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
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.
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.
- 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
- The ldap_upstream_watcher.go controller validates the bind secret and
uses the Conditions to report errors. Shares some condition reporting
logic with its sibling controller oidc_upstream_watcher.go, to the
extent which is convenient without generics in golang.
- Add some fields to LDAPIdentityProvider that we will need to be able
to search for users during login
- Enhance TestSupervisorLogin to test logging in using an upstream LDAP
identity provider. Part of this new test is skipped for now because
we haven't written the corresponding production code to make it
pass yet.
- Some refactoring and enhancement to env.go and the corresponding env
vars to support the new upstream LDAP provider integration tests.
- Use docker.io/bitnami/openldap for our test LDAP server instead of our
own fork now that they have fixed the bug that we reported.

The goal here was to start on an integration test to get us closer to the red
test that we want so we can start working on LDAP.
