The token endpoint handled the scope parameter incorrectly for all of
the three handled grant types:
1. For "authorization_code" grant type the scope parameter in the token
request should not be respected but the scope should be taken from
the authorization code. It was not totally ignored, but rather the
scope parameter of the token request was used for the generated ID
token. This had two consequences:
* Spec conforming implementations of authorization code flow
didn't get correct ID tokens, since they usually don't pass
scope parameter with the token request.
* It's possible to get a broader scope for the ID token than what
is authorized by the user in the original authorization code
request.
2. For "refresh_token" grant type the scope parameter in the token
request should only allow narrowing down the scope. It wasn't
narrowed, but rather the original auth code scope was used for the
access token and the passed in scope parameter was used for the ID
token (again allowing unauthorized scopes in the ID token).
3. For "password" grant type the scope parameter in the token request
should be respected. The problem with this was that it wasn't
properly splitted when passed to ID token creation.
Fixes#186
* Test redirect_uri construction
This was a test marked as TODO.
* Remove duplicate test
* Add tests to exactly match redirect URIs
* Redirect URIs must match exactly.
To quote from the specification at
http://openid.net/specs/openid-connect-core-1_0.html#AuthRequest:
Redirection URI to which the response will be sent. This URI MUST
exactly match one of the Redirection URI values for the Client
pre-registered at the OpenID Provider, with the matching performed as
described in Section 6.2.1 of [RFC3986] (Simple String Comparison).
* Log create_uri_response exceptions to logger.exception
* Support grant type password - basics
* Add tests for Resource Owner Password Credentials Flow
* Password Grant -Response according to specification
* Better tests for errors, disable grant type password by default
* Add documentation for grant type password
* User authentication failure to return 403
* Add id_token to response
* skipping consent only works for confidential clients
* fix URI fragment
example not working URL `http://localhost:8100/#/auth/callback/`
* OIDC_POST_END_SESSION_HOOK + tests
* Explicit function naming
* Remove print statements
* No need for semicolons, this is Python
* Update CHANGELOG.md
* fixed logger message
* Improved `exp` value calculation
* rename OIDC_POST_END_SESSION_HOOK to OIDC_AFTER_END_SESSION_HOOK
* added docs for OIDC_AFTER_END_SESSION_HOOK
* Replaces `LOGIN_URL` with `OIDC_LOGIN_URL`
so users can use a different login path for their oidc requests.
* Adds a setting variable for custom template paths
* Updates documentation
* Fixed bad try/except/finally block
* Adds test for OIDC_TEMPLATES settings
* Determine value for op_browser_state from session_key or default
* Do not use cookie for browser_state. It may not yet be there
* Add docs on new setting
OIDC_UNAUTHENTICATED_SESSION_MANAGEMENT_KEY
* Fix compatibility for older versions of Django
* solved merging typo for missing @property
Use `time.time()` rather than `timezone.now()` for generating the unix
timestamps. This avoids conversion between year-month-day-hh-mm-ss
formatted timestamp vs. unix timestamp and is therefore simpler and more
robust.
Add a test case for this too and amend test_token_endpoint, since it
used to mock timezone.now, but now it needs to mock time.time.
In some cases a client will provide a redirect URI with a query string.
In these cases the client redirect URI should still still match a
registered redirect URI and not result in a failure.
