Mateusz Mandera 869b57b7f7 ldap tests: Change TestQueryLDAP tests to use the test ldap directory.
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.

Mateusz Mandera 68f4cd1e94 ldap: Extract ldap user -> django username mapping logic to a function.
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.

Mateusz Mandera 3699fe28f8 ldap: Use email search in django_to_ldap_username.
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.

Mateusz Mandera fea4d0b2be ldap: Do a proper search for email in email_belongs_to_ldap.
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.

Mateusz Mandera 2ce2024bd7 ldap: Fix unintended user deactivation in case of connection failure.
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.

Anders Kaseorg fd7803e7f4 settings: Unset STATIC_ROOT in development.
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.

Harshit Bansal bf14a0af4d auth: Migrate google auth to python-social-auth.
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

added some GitHub-specific authentication backend tests to the common
test class.

Fix this by moving them to the GitHub-specific subclass.

Shubham Padia 80a3651cf3 auth: Let user choose emails in GitHub auth.
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.

Anders Kaseorg 802d3dbbf4 authenticate: Use keyword-only parameters.
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.

Harshit Bansal a6e523f9e4 ldap: Ensure email is valid for realm before registering.
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.
