Mateusz Mandera 4dc3ed36c3 auth: Add initial SAML authentication support.
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.

Mateusz Mandera 82f923c27a social auth: Validate email in backends without get_verified_emails.
If the social backend doesn't have get_verified_emails emails, and we
simply grab kwargs["details"].get("email") for the email, we should
still validate it is correct.
Needed for SAML. This will get covered by tests in upcoming commits that
add SAML support.

Mateusz Mandera 935702b6ec auth: Rename any_oauth_backend_enabled to any_social_backend_enabled.
any_oauth_backend_enabled is all about whether we will have extra
buttons on the login/register pages for logging in with some non-native
backends (like Github, Google etc.). And this isn't about specifically
oauth backends, but generally "social" backends - that may not rely
specifically rely on Oauth. This will have more concrete relevance when
SAML authentication is added - which will be a "social" backend,
requiring an additional button, but not Oauth-based.

Mateusz Mandera 050f814e47 auth: Clean up SOCIAL_AUTH_BACKENDS / OAUTH_BACKEND_NAMES lists.
SOCIAL_AUTH_BACKEND / OAUTH_BACKEND_NAMES are currently the same
backends. All Oauth backends are social, and all social are oauth.
So we get rid of OAUTH_BACKEND_NAMES and use only SOCIAL_AUTH_BACKENDS.

Tim Abbott 7e75f987df ldap: Fix logging of warning for deactivated users.

Tim Abbott d1a2784d52 ldap: Fix attempting to sync data for deactivated users.
The order of operations for our LDAP synchronization code wasn't

deactivated users.

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.

Alexandra Ciobica f109dcce9c auth: Add logic for avatars to the GitHub auth email selection page.
For the emails that are associated to an existing account in an
organisation, the avatars will be displayed in the email selection
page.  This includes avatar data in what is passed to the page.

Added `avatar_urls` to the context in `test_templates.py`.

Alexandra Ciobica d4ccd73ae3 auth: Remove `@users.noreply.github.com` from the email selection list.
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.

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.

vinitS101 04f3fce761 ldap: Fix LDAP avatar synchronization to check if avatar has changed.
When "manage.py sync_ldap_user_data" is run, user avatars are now only
updated if they have changed in LDAP.

Fixes #12381.

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.

vinitS101 a6eda858d0 ldap: Fix avatar sync not working with the S3 backend.
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.

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.

Tim Abbott b4d47b129d backends: Further optimize auth_enabled_helper.

common_context.

Harshit Bansal 262eb42b77 auth: Reverse the `sort_order` parameter's semantics.

`sort_order` parameter then it will sorted to the bottom not at the
top.

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.

Vishnu Ks 868a763cec auth2: Don't use session for passing multiuse invite key.
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.
