This fixes a small mistake in PR #1864. When the "pinniped login oidc"
CLI command is deciding if the RFC8693 token exchange is needed, it
should not look at the expiry of the ID token. This mistake would cause
the RFC8693 token exchange to happen when the OIDC provider is not
a Pinniped Supervisor, which would fail because most other providers
do not support that type of token exchange.
It does not matter if the current ID token is close to expiring when
deciding if the RFC8693 token exchange is needed, because the token
exchange is going to yield a new ID token anyway. It does matter if the
current ID token is close to expiring if the CLI decides that it is
not going to perform the token exchange, and this commit does not change
that logic.
Background: For dynamic clients, the groups scope is not always allowed
and/or requested by the client, so it will not always be granted by the
Supervisor for an authorization request.
Previously, when the groups scope was not granted, we would skip
searching for upstream groups in some scenarios.
This commit changes the behavior of authorization flows so that even
when the groups scope is not granted we still search for the upstream
group memberships as configured, and we pass the upstream group
memberships into any configured identity transformations. The identity
transformations could potentially reject the user's authentication based
on their upstream group membership.
When the groups scope is not granted, we don't include the groups in
the final Supervisor-issued ID token. This behavior is not changed.
Each endpoint handler is now responsible for applying the identity
transformations and creating most of the session data, rather than each
implementation of the upstream IDP interface. This shares code better,
and reduces the responsibilities of the implementations of the IDP
interface by letting them focus more on the upstream stuff.
Also refactor the parameters and return types of the IDP interfaces to
make them more clear, and because they can be more focused on upstream
identities (pre-identity transformation). This clarifies the
responsibilities of the implementations of the IDP interface.
Create an interface to abstract the upstream IDP from the
authorize, IDP discovery, callback, choose IDP, and login
endpoints. This commit does not refactor the token endpoint,
which will be refactored in a similar way in the next commit.
- continued refactoring the auth handler to share more code between
the two supported browserless flows: OIDC and LDAP/AD
- the upstreamldap package should not know about the concept of
OIDC granted scopes, so refactored it to be a skipGroups bool
- Simplify the error handling in the authorize endpoint by making the
private helper functions return fosite-style errors, and having
one place that writes those errors to the response.
- Some types of errors were previously returned as regular http-style
errors. Those have all been converted to be returned as oauth-style
errors (which can be redirects to the client), except for http method
not found errors. This is a change in behavior from the client's point
of view, but only when those unexpected errors happen. These types of
errors are more consistent with RFC6749 section 4.1.2.1.
- Avoids using the httperr package for error handling.
- Create a struct for the handler as a first step toward making smaller
functions with fewer parameters.
In the RFC8693 token exchange, the CLI sends your access token and
receives in exchange a new cluster-scoped ID token.
Fix a bug in the CLI. Whenever the "pinniped login oidc" command was
planning to perform the RFC8693 token exchange, it failed to check if
the cached access token was still valid before performing the exchange,
which sends the access token. It instead checked if the cached ID token
was still valid, but that it not relevant in this situation because the
ID token is not going to be used for anything (instead the new ID token
returned by the RFC8693 token exchange will be used for auth).
This bug doesn't actually matter today, because the Supervisor-issued
access and ID tokens always both have the same 2-minute lifetimes.
However, future enhancements may cause them to have different lifetimes
in certain circumstances. Fixing this CLI bug now to prepare for those
potential future enhancements.
Goboring only allows TLS 1.2.
The next goboring will allow both TLS 1.2 and TLS 1.3. We got a preview
of this when the Go team upgraded goboring in Go 1.21.6, but then
downgraded it again in the next Go releases.
When the Go team eventually upgrades goboring again, then we can
revert this commit to bring back TLS 1.3 support in FIPS mode.
- Current goboring only allows TLS 1.2.
