Instead of mocking the _LDAPUser class, these tests can now take
advantage of the test directory that other ldap are using. After these
changes, test_query_email_attr also verifies that query_ldap can
successfully be used to query by user email, if email search is
configured.
Fixes#11878
Instead of a confusing mix of django_auth_backed applying
ldap_to_django_username in its internals for one part of the
translation, and then custom logic for grabbing it from the email
attribute of the ldapuser in ZulipLDAPAuthBackend.get_or_build_user
for the second part of the translation,
we put all the logic in a single function user_email_from_ldapuser
which will be used by get_or_build of both ZulipLDAPUserPopulator and
ZulipLDAPAuthBackend.
This, building on the previous commits with the email search feature,
fixes the ldap sync bug from issue #11878.
If we can get upstream django-auth-ldap to merge
https://github.com/django-auth-ldap/django-auth-ldap/pull/154, we'll
be able to go back to using the version of ldap_to_django_username
that accepts a _LDAPUser object.
With this, django_to_ldap_username can take an email and find the ldap
username of the ldap user who has this email - if email search is
configured.
This allows successful authenticate() with ldap email and ldap password,
instead of ldap username. This is especially useful because when
a user wants to fetch their api key, the server attempts authenticate
with user_profile.email - and this used to fail if the user was an ldap
user (because the ldap username was required to authenticate
succesfully). See issue #9277.
This fixes a collection of bugs surrounding LDAP configurations A and
C (i.e. LDAP_APPEND_DOMAIN=None) with EmailAuthBackend also enabled.
The core problem was that our desired security model in that setting
of requiring LDAP authentication for accounts managed by LDAP was not
implementable without a way to
Now admins can configure an LDAPSearch query that will find if there
are users in LDAP that have the email address and
email_belongs_to_ldap() will take advantage of that - no longer
returning True in response to all requests and thus blocking email
backend authentication.
In the documentation, we describe this as mandatory configuration for
users (and likely will make it so soon in the code) because the
failure modes for this not being configured are confusing.
But making that change is pending work to improve the relevant error
messages.
Fixes#11715.
MigrationsTestCase is intentionally omitted from this, since migrations
tests are different in their nature and so whatever setUp()
ZulipTestCase may do in the future, MigrationsTestCase may not
necessarily want to replicate.
There are a few outstanding issues that we expect to resolve beforce
including this in a release, but this is good checkpoint to merge.
This PR is a collaboration with Tim Abbott.
Fixes#716.
Also cleans up the interface between the management command and the
LDAP backends code to not guess/recompute under what circumstances
what should be logged.

The order of operations for our LDAP synchronization code wasn't
correct: We would run the code to sync avatars (etc.) even for
deactivated users.
Thanks to niels for the report.

Fixes#13130.
django_auth_ldap doesn't give any other way of detecting that LDAPError
happened other than catching the signal it emits - so we have to
register a receiver. In the receiver we just raise our own Exception
which will properly propagate without being silenced by
django_auth_ldap. This will stop execution before the user gets
deactivated.
I changed the class of the title in order to use the same styling as the
other similar pages (like `/accounts/go` or `/login`).
Changed the related test.
Apparently GitHub changed the email address for these; we need to
update our code accordingly.
One cannot receive emails on the username@users.noreply.github.com, so
if someone tries creating an account with this email address, that
person would not be able to verify the account.
Django’s default FileSystemFinder disallows STATICFILES_DIRS from
containing STATIC_ROOT (by raising an ImproperlyConfigured exception),
because STATIC_ROOT is supposed to be the result of collecting all the
static files in the project, not one of the potentially many sources
of static files.

This replaces the two custom Google authentication backends originally
written in 2012 with using the shared python-social-auth codebase that
we already use for the GitHub authentication backend. These are:
* GoogleMobileOauth2Backend, the ancient code path for mobile
authentication last used by the EOL original Zulip Android app.
* The `finish_google_oauth2` code path in zerver/views/auth.py, which
was the webapp (and modern mobile app) Google authentication code
path.
This change doesn't fix any known bugs; its main benefit is that we
get to remove hundreds of lines of security-sensitive semi-duplicated
code, replacing it with a widely trusted, high quality third-party
library.
During the time between when we refactored the GitHub authentication
backend to use SocialAuthBase and now (when we're about to migrate
GoogleAuthBackend to use that code path as well), we accidentally
added some GitHub-specific authentication backend tests to the common
test class.
Fix this by moving them to the GitHub-specific subclass.
Previously, our Github authentication backend just used the user's
primary email address associated with GitHub, which was a reasonable
default, but quite annoying for users who have several email addresses
associated with their GitHub account.
We fix this, by adding a new screen where users can select which of
their (verified) GitHub email addresses to use for authentication.
This is implemented using the "partial" feature of the
python-social-auth pipeline system.
Each email is displayed as a button. Clicking on that button chooses
the email. The email value is stored in a hidden input above the
button. The `primary_email` is displayed on top followed by
`verified_non_primary_emails`. Backend name is also passed as
`backend` to the template, which in our case is GitHub.
Fixes#9876.
This fixes an issue that caused LDAP synchronization to fail for
avatars. The problem occurred due to the lack of a 'name' attribute
on the BytesIO object that we pass to the upload backend (which is
only used in the S3 backend for computing Content-Type).
Fixes#12411.
Since positional arguments are interpreted differently by different
backends in Django's authentication backend system, it’s safer to
disallow them.
This had been the motivation for previously declaring the parameters
with default values when we were on Python 2, but that was not super
effective because Python has no rule against positional default
arguments and that convention for our authentication backends was
solely enforced by code review.

This cleans up the pattern for how we check which user is logged in
during Zulip's backend unit tests to be much more readable (replacing
the arcane session code that does this check).
Fixes#12273.
When running the test_query_email_attr test in reverse, the test failed
because self._LDAPUser.attrs was being modified and it was being shared
with other tests.
This makes the implementation of `get_realm` consistent with its
declared return type of `Realm` rather than `Optional[Realm]`.
Fixes#12263.

See the comment, but this is a significant performance optimization
for all of our pages using common_context, because this code path is
called more than a dozen times (recursively) by common_context.
Apparently, our invalid realm error page had HTTP status 200, which
could be confusing and in particular broken our mobile app's error
handling for this case.
Previously, the LDAP authentication model ignored the realm-level
settings for who can join a realm. This was sort of reasonable at the
time, because the original LDAP auth was an SSO solution that didn't
allow multiple realms, and so one could fully configure authentication
settings on the LDAP side. But now that we allow multiple realms with
the LDAP backend, one could easily imagine wanting different
restrictions on them, and so it makes sense to add this enforcement.
Earlier the behavior was to raise an exception thereby stopping the
whole sync. Now we log an error message and skip the field. Also
fixes the `query_ldap` command to report missing fields without
error.
Fixes: #11780.
The night logo synchronization on the settings page was perfect, but
the actual display logic had a few problems:
* We were including the realm_logo in context_processors, even though
it is only used in home.py.
* We used different variable names for the templating in navbar.html
than anywhere else the codebase.
* The behavior that the night logo would default to the day logo if
only one was uploaded was not correctly implemented for the navbar
position, either in the synchronization for updates code or the
logic in the navbar.html templates.
For Google auth, the multiuse invite key should be stored in the
csrf_state sent to google along with other values like is_signup,
mobile_flow_otp.
For social auth, the multiuse invite key should be passed as params to
the social-auth backend. The passing of the key is handled by
social_auth pipeline and made available to us when the auth is
completed.
Extracts out common tests so that future social-auth backends can
be tested without duplicating tests. I have been careful to not
change any testing logic.
As part of Google+ being removed, they've eliminated support for the
/plus/v1/people/me endpoint. Replace it with the very similar
/oauth2/v3/userinfo endpoint.
`fakeldap` assumes every attribute to be a multi-value attribute
while making comparison in `_comapare_s()` and so while making
comparisons for password it gives a false positive. The result
of this was that it was possible to login in the dev environment
using LDAP using a substring of the password. For example, if the
LDAP password is `ldapuser1` even entering `u` would log you in.
We had an inconsistent behavior when `LDAP_APPEND_DOMAIN` was set
in that we allowed user to enter username instead of his email in
the auth form but later the workflow failed due to a small bug.
Fixes: #10917.
This adds a new realm_logo field, which is a horizontal-format logo to
be displayed in the top-left corner of the webapp, and any other
places where we might want a wide-format branding of the organization.
Tweaked significantly by tabbott to rebase, fix styling, etc.
Fixing the styling of this feature's loading indicator caused me to
notice the loading indicator for the realm_icon feature was also ugly,
so I fixed that too.
Fixes#7995.
This should make life a lot more convenient for organizations that use
the LDAP integration and have their avatars in LDAP already.
This hasn't been end-to-end tested against LDAP yet, so there may be
some minor revisions, but fundamentally, it works, has automated
tests, and should be easy to maintain.
Fixes#286.
This styles the avatar and username that show when the registering
user is importing their settings from an existing Zulip account.
Tweaked by tabbott to fix the test/linter failures, a bit of styling,
and tag strings for translation.
Apparently, while the main code path through
login_or_register_remote_user was correctly calling
remote_user_to_email(username) to get a proper email address for
situations where auth username != email (i.e. when SSO_APPEND_DOMAIN
is set), we neglected to do so in the mobile_flow_otp corner case.
Fixes#11005.
Removes email_not_verified option. That option was used to assign
email_data a different set of emails for a test. Instead of that,
this refactor allows to specify the email_data itself in the function
which calls github_oauth2_test. Flags like email_not_verified are
generally used in one test. This is a preparatory refactor for
choose email screen which may have introduced multiple flags otherwise.
The email_list returned has the primary email as the first element.
Testing: The order of the emails in the test was changed to put a
verified email before the primary one. The tests would fail without
this commit's change after the changes in the order of test emails.
Fixes part of #10297.
Use FAKE_LDAP_NUM_USERS which specifies the number of LDAP users
instead of FAKE_LDAP_EXTRA_USERS which specified the number of
extra users.
The output of generate_dev_ldap_dir was being tested against the fixture
located at zerver/tests/fixtures/ldap_dir.json. This didn't make much sense
as generate_dev_ldap_dir was itself used by developers to generate/update
the fixtures. Instead, test_generate_dev_ldap_dir checks the structure of
the dict returned by generate_dev_ldap_dir. The structure is checked by
regex checks, checking whether the dict contains some keys or not, etc.
Issue: When you created a new organization with /new, the "new login"
emails were emailed. We previously had a hack of adding the
.just_registered property to the user Python object to attempt to
prevent the emails, and checking that in zerver/signals.py. This
commit gets rid of the .just_registered check.
Instead of the .just_registered check, this checks if the user has
joined more than a minute before.
A test test_dont_send_login_emails_for_new_user_registration_logins
already exists.
Tweaked by tabbott to introduce the constant JUST_CREATED_THRESHOLD.
Fixes#10179.
Generates ldap_dir based on the mode and the no. of extra users.
It supports three modes, 'a', 'b' and 'c', description for which
can be found in prod_settings_templates.py.
Now reading API keys from a user is done with the get_api_key wrapper
method, rather than directly fetching it from the user object.
Also, every place where an action should be done for each API key is now
using get_all_api_keys. This method returns for the moment a single-item
list, containing the specified user's API key.
This commit is the first step towards allowing users have multiple API
keys.
This adds a new settings, SOCIAL_AUTH_SUBDOMAIN, which specifies which
domain should be used for GitHub auth and other python-social-auth
backends.
If one is running a single-realm Zulip server like chat.zulip.org, one
doesn't need to use this setting, but for multi-realm servers using
social auth, this fixes an annoying bug where the session cookie that
python-social-auth sets early in the auth process on the root domain
ends up masking the session cookie that would have been used to
determine a user is logged in. The end result was that logging in
with GitHub on one domain on a multi-realm server like zulipchat.com
would appear to log you out from all the others!
We fix this by moving python-social-auth to a separate subdomain.
Fixes: #9847.
We need to do a small monkey-patching of python-social-auth to ensure
that it doesn't 500 the request when a user does something funny in
their browser (e.g. using the back button in the auth flow) that is
fundamentally a user error, not a server error.
This was present in the pre-rewrite version of our Social auth
codebase, without clear documentation; I've fixed the explanation
part here.
It's perhaps worth investigating with the core social auth team
whether there's a better way to do this.
It's possible to make GitHub social authentication support letting the
user pick which of their verified email addresses to pick, using the
python-social-auth pipeline feature. We need to add an additional
screen to let the user pick, so we're not adding support for that now,
but this at least migrates this to use the data set of all emails that
have been verified as associated with the user's GitHub account (and
we just assume the user wants their primary email).
This also fixes the inability for very old GitHub accounts (where the
`email` field in the details might be a string the user wanted on
their GitHub profile page) to using GitHub auth to login.
Fixes#9127.
This new implementation model is a lot cleaner and should extend
better to the non-oauth backend supported by python-social-auth (since
we're not relying on monkey-patching `do_auth` in the OAuth backend
base class).
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.
