This revised GitHub auth backend test is inspired by the end-to-end
flow model of the Google auth backend test. My hope is that we will
be able to migrate the rest of the important cases in the GitHub auth
backend tests to this model and then delete what is now
GitHubAuthBackendLegacyTest.
The next step after that will be to merge the GitHub and Google auth
tests (since actually, the actual test functions are basically
identical between the two).
If a user's account has been deactivated, we want to provide a special
error message that makes clear what's going on.
Future work is to provide some administrative controls on whether a
user should be able to re-activate their account.
A common path is a new user goes to realm_uri, which redirects to
realm_uri/login, and clicks the google auth button thinking it is a
registration button.
This commit just changes the wording on the page they land on to be
friendlier for that use case.
The main change here is to send a proper confirmation link to the
frontend in the `confirm_continue_registration` code path even if the
user didn't request signup, so that we don't need to re-authenticate
the user's control over their email address in that flow.
This also lets us delete some now-unnecessary code: The
`invalid_email` case is now handled by HomepageForm.is_valid(), which
has nice error handling, so we no longer need logic in the context
computation or template for `confirm_continue_registration` for the
corner case where the user somehow has an invalid email address
authenticated.
We split one GitHub auth backend test to now cover both corner cases
(invalid email for realm, and valid email for realm), and rewrite the
Google auth test for this code path as well.
Fixes#5895.
By moving all of the logic related to the is_signup flag into
maybe_send_to_registration, we make the login_or_register_remote_user
function quite clean and readable.
The next step is to make maybe_send_to_registration less of a
disaster.
The code in maybe_send_to_registration incorrectly used the
`get_realm_from_request` function to fetch the subdomain. This usage
was incorrect in a way that should have been irrelevant, because that
function only differs if there's a logged-in user, and in this code
path, a user is never logged in (it's the code path for logged-out
users trying to sign up).
This this bug could confuse unit tests that might run with a logged-in
client session. This made it possible for several of our GitHub auth
tests to have a totally invalid subdomain value (the root domain).
Fixing that bug in the tests, in turn, let us delete a code path in
the GitHub auth backend logic in `backends.py` that is impossible in
production, and had just been left around for these broken tests.
This code path has actually been dead for a while (since
`invalid_subdomain` gets set to True only when `user_profile` is
`None`). We might want to re-introduce it later, but for now, we
eliminate it and the artificial test that provided it with test
coverage.
This is a mobile-specific endpoint used for logging into a dev server.
On mobile without this realm_uri it's impossible to send a login request
to the corresponding realm on the dev server and proceed further; we can
only guess, which doesn't work for using multiple realms.
Also rename the endpoint to reflect the additional data.
Testing Plan:
Sent a request to the endpoint, and inspected the result.
[greg: renamed function to match, squashed renames with data change,
and adjusted commit message.]
Issue #2088 asked for a wrapper to be created for
`create_stream_if_needed` (called `ensure_stream`) for the 25 times that
`create_stream_if_needed` is called and ignores whether the stream was
created. This commit replaces relevant occurences of
`create_stream_if_needed` with `ensure_stream`, including imports.
The changes weren't significant enough to add any tests or do any
additional manual testing.
The refactoring intended to make the API easier to use in most cases.
The majority of uses of `create_stream_if_needed` ignored the second
parameter.
Fixes: #2088.
It's possible that this won't work with some versions of the
third-party backend, but tabbott has tested carefully that it does
work correctly with the Apache basic auth backend in our test
environment.
In this commit we start to support redirects to urls supplied as a
'next' param for the following two backends:
* GoogleOAuth2 based backend.
* GitHubAuthBackend.
This is necessary for mobile apps to do the right thing when only
RemoteUserBackend is enabled, namely, directly redirect to the
third-party SSO auth site as soon as the user enters the server URL
(no need to display a login form, since it'll be useless).
Previously, we used to raise an exception if the direct dev login code
path was attempted when:
* we were running under production environment.
* dev. login was not enabled.
Now we redirect to an error page and give an explanatory message to the
user.
Fixes#8249.
When the answer is False, this will allow the mobile app to show a
warning that push notifications will not work and the server admin
should set them up.
Based partly on Kunal's PR #7810. Provides the necessary backend API
for zulip/zulip-mobile#1507.
We keep having to change the same thing in three places here; and also
the duplicates have accumulated unnecessary variation that makes it
hard to see what's actually supposed to be different and not different
in the three cases.
For example, this means that if a user already has an account on one
realm and they try to make an account on another by hitting "Sign in
with Google" (rather than following the little "Register" link to a
"Sign up with Google" button instead), they'll get to make an account
instead of getting an error.
Until very recently, if the user existed on another realm, any attempt
to register with that email address had to fail in the end, so this
logic gave the user a useful error message early. We introduced it in
c23aaa178 "GitHub: Show error on login page for wrong subdomain"
back in 2016-10 for that purpose. No longer! We now support reusing
an email on multiple realms, so we let the user proceed instead.
This function's interface is kind of confusing, but I believe when its
callers use it properly, `invalid_subdomain` should only ever be true
when `user_profile` is None -- in which case the revised
`invalid_subdomain` condition in this commit can never actually fire,
and the `invalid_subdomain` parameter no longer has any effect. (At
least some unit tests call this function improperly in that respect.)
I've kept this commit to a minimal change, but it would be a good
followup to go through the call sites, verify that, eliminate the use
of `invalid_subdomain`, then remove it from the function entirely.
This completes the last commit's work to fix CVE-2017-0910, applying
to any invite links already created before the fix was deployed. With
this change, all new-user registrations must match an explicit realm
in the PreregistrationUser row, except when creating a new realm.
[greg: rewrote commit message]
This deletes the old mock-covered test for this, which was mostly
useless. We have a much less messy test, which we extend to provide
the same test coverage the old one did.
While the result was the same before, this makes it more obvious.
This code path was only required because we had remote_user set as a
positional argument here, and thus we'd be running this auth backend's
code when actually using another auth backend (due to how Django auth
backends are selected based on argument signature).
The cookie mechanism only works when passing the login token to a
subdomain. URLs work across domains, which is why they're the
standard transport for SSO on the web. Switch to URLs.
Tweaked by tabbott to add a test for an expired token.
This makes the tests a little cleaner in itself, and also prepares
them to adjust with less churn when we change how
redirect_and_log_into_subdomain passes the signed token.
If an organization doesn't have the EmailAuthBackend (which allows
password auth) enabled, then our password reset form doesn't do
anything, so we should hide it in the UI.
Most of the paths leading through this except clause were cut in
73e8bba37 "ldap auth: Reassure django_auth_ldap". The remaining one
had no test coverage -- the case that leads to it had a narrow unit
test, but no test had the exception actually propagate here. As a
result, the clause was mistakenly cut, in commit
8d7f961a6 "LDAP: Remove now-impossible except clause.", which could
lead to an uncaught exception in production.
Restore the except clause, and add a test for it.
This makes GoogleSubdomainLoginTest consistently access subdomains the
standard way, replacing the original hacky approach it had that
predated the library.
The plan is to have everything expect subdomains, so it makes sense to
move these tests to the subdomains-only test class and style.
Most of the remaining GoogleLoginTest tests are now either duplicates
or basic API-level tests where subdomains are irrelevant.
This commit enables user to authenticate with any attribute set in
AUTH_LDAP_USER_SEARCH given that LDAP_EMAIL_ATTR is set to an email
attributes in the ldap server. Thus email and username can be
completely unrelated.
With some tweaks by tabbott to squash in the documentation and make it
work on older servers.
Previously, we didn't pass customized HTTP_HOST headers when making
network requests. As we move towards a world where everything is on a
subdomain, we'll want to start doing that.
The vast majority of our test code is written to interact with the
default "zulip" realm, which has a subdomain of "zulip". While
probably longer-term, we'll wish this was the root domain, for now, we
need to make our HTTP requests match what is expected by the test
code.
This commit almost certainly introduces some weird bugs where code was
expecting a different subdomain but the tests doesn't fail yet. It's
not clear how to find all of these, but I've done some grepping.
Previously, Zulip's server logs would not show which user or client
was involved in login or user registration actions, which made
debugging more annoying than it needed to be.
This should significantly improve the user experience for new users
signing up with GitHub/Google auth. It comes complete with tests for
the various cases. Further work may be needed for LDAP to not prompt
for a password, however.
Fixes#886.
This allows us to go to Registration form directly. This behaviour is
similar to what we follow in GitHub oAuth. Before this, in registration
flow if an account was not found, user was asked if they wanted to go to
registration flow. This confirmation behavior is followed for login
oauth path.
This error isn't saying that any kind of authentication or
authorization failed -- it's just a validation error like
any other validation error in the values the user is asking to
set. The thought of authentication comes into it only because
the setting happens to be *about* authentication.
Fix the error to look like the other validation errors around it,
rather than give a 403 HTTP status code and a "reason" field that
mimics the "reason" fields in `api_fetch_api_key`.
Currently we only pass headers in the first client_get call but
sometimes the effective request which reaches the view is through
a later call to the client_get in this function. Due to which
headers are not passed.
