Mateusz Mandera 86c330b752 social_auth: Fix handling of user errors in the authentication process.
The code didn't account for existence of SOCIAL_AUTH_SUBDOMAIN. So the
redirects would happen to endpoints on the SOCIAL_AUTH_SUBDOMAIN, which
is incorrect. The redirects should happen to the realm from which the
user came.

PIG208 495a8476be tests: Use assertion to enforce None-checks in tests.
This fixes a batch of mypy errors of the following format:
'Item "None" of "Optional[Something]" has no attribute "abc"

Since we have already been recklessly using these attritbutes
in the tests, adding assertions beforehand is justified presuming
that they oughtn't to be None.

Mateusz Mandera 18dab5619c ldap: Fix ldap access control tests.
These tests didn't configure ldap settings correctly and as a result,
the user involved in these tests wasn't actually hamlet@zulip.com, but a
new, malformed user with email "hamlet" that was being created by the
ldap auto-registration codepath. This wasn't caught because the codepath
didn't validate the email address and thus created such a malformed user
silently.

Mateusz Mandera c54b48452d saml: Support syncing custom profile fields with SAML attributes.
Fixes #17277.

The main limitation of this implementation is that the sync happens if
the user authing already exists. This means that a new user going
through the sign up flow will not have their custom fields synced upon
finishing it. The fields will get synced on their consecutive log in via
SAML in the future. This can be addressed in the future by moving the
syncing code further down the codepaths to login_or_register_remote_user
and plumbing the data through to the user creation process.

We detail that limitation in the documentation.

Dinesh 00e0b63c6c auth: Handle user_profile.check_password raising PasswordTooWeakError.
user_profile.check_password(password) in authenticate of
EmailAuthBackend can raise PasswordTooWeakError; this happens when the
user's password is weaker than the current required policies and needs
to be rehashed (E.g. because, as in Django 3.2, the minimum salt
entropy increased).

This is a very rare case, but still needs a good user-facing error
message. We raise a json error to handle this with a user-facing error
message.

See this comment by Mateusz Mandera for a detailed explanation
about this case along with a traceback it generates.

Strifel 209c89be10 ldap: Add option to limit user access to certain realms.
This adds an option for restricting a ldap user

This is done by configuring an attribute mapping of "org_membership"
to an ldap attribute that will contain the list of subdomains the ldap
user is allowed to access. This is analogous to how it's done in SAML.

Mateusz Mandera 48f80fcb0a auth: Expect name in request params in Apple auth.
The name used to be included in the id_token, but this seems to have
been changed by Apple and now it's sent in the `user` request param.

https://github.com/python-social-auth/social-core/pull/483 is the
upstream PR for this - but upstream is currently unmaintained, so we
have to monkey patch.

We also alter the tests to reflect this situation. Tests no longer put
the name in the id_token, but rather in the `user` request param in the
browser flow, just like it happens in reality.

An adaptation has to be made in the native flow - since the name won't
be included by Apple in the id_token anymore, the app, when POSTing
to the /complete/apple/ endpoint,
can (and should for better user experience)
add the `user` param formatted as json of
{"email": "hamlet@zulip.com", "name": {"firstName": "Full", "lastName": "Name"}}
dict. This is also reflected by the change in the
native flow tests.

Dinesh acca870480 tests: Add a dummy request to self.client.login().
A later commit alters `authenticate` of EmailAuthBackend to
add a store `needs_to_change_password` variable to session
which is useful to insist users on changing their weak password.

The tests start failing with that change because client.login()
runs `authenticate` without a `request` object. So, this commit
sends a request object with `request.session=self.client.session`
to self.client.login() in tests wherever needed.

Dinesh 232eb8b7cf auth: Render config error page on configuration error.
We previously used to to redirect to config error page with

URL where configuration error is encountered. This way when
conifguration error is fixed the user can refresh to continue
normally or go back to login page from the link provided to
choose any other backend auth.

Also moved those URLs to dev_urls.py so that they can be easily
accessed to work on styling etc.

In tests, removed some of the asserts checking status code to be 200
as the function `assert_in_success_response` does that check.

Anders Kaseorg b7b7475672 python: Use standard secrets module to generate random tokens.
There are three functional side effects:

• Correct an insignificant but mathematically offensive bias toward
repeated characters in generate_api_key introduced in commit
47b4283c4b4c70ecde4d3c8de871c90ee2506d87; its entropy is increased
from 190.52864 bits to 190.53428 bits.

• Use the base32 alphabet in confirmation.models.generate_key; its
entropy is reduced from 124.07820 bits to the documented 120 bits, but
now it uses 1 syscall instead of 24.

• Use the base32 alphabet in get_bigbluebutton_url; its entropy is
reduced from 51.69925 bits to 50 bits, but now it uses 1 syscall
instead of 10.

(The base32 alphabet is A-Z 2-7.  We could probably replace all of
these with plain secrets.token_urlsafe, since I expect most callers
can handle the full urlsafe_b64 alphabet A-Z a-z 0-9 - _ without
problems.)

Dinesh c15d7e3202 requirements: Update social-auth-core to latest version.
Uses git release as this version 3.4.0 is not released to pypi.
This is required for removing some overriden functions of

With the update we also make following changes:

* Fix full name being populated as "None None".
c5c74f27dd that's included in update assigns first_name and last_name
to None when no name is provided by apple. Due to this our
code is filling return_data['full_name'] to 'None None'.
This commit fixes it by making first and last name strings empty.

* Remove decode_id_token override.
Python social auth merged the PR we sent including the changes
we made to decode_id_token function. So, now there is no
necessity for the override.

* Add _AUDIENCE setting in computed_settings.py.
`decode_id_token` is dependent on this setting.

    - We change functions like do_create_user,

which organization each user can access.

Anders Kaseorg 7e9db327b3 request: Improve validator type so mypy can check it against REQ.
Old: a validator returns None on success and returns an error string
on error.

New: a validator returns the validated value on success and raises
ValidationError on error.

This allows mypy to catch mismatches between the annotated type of a
REQ parameter and the type that the validator actually validates.

Mateusz Mandera 8d2d64c100 CVE-2020-14215: Fix validation in PreregistrationUser queries.
The most import change here is the one in maybe_send_to_registration
codepath, as the insufficient validation there could lead to fetching
an expired PreregistrationUser that was invited as an administrator
admin even years ago, leading to this registration ending up in the
new user being a realm administrator.

Combined with the buggy migration in
0198_preregistrationuser_invited_as.py, this led to users incorrectly
joining as organizations administrators by accident.  But even without
that bug, this issue could have allowed a user who was invited as an
administrator but then had that invitation expire and then joined via
social authentication incorrectly join as an organization administrator.

The second change is in ConfirmationEmailWorker, where this wasn't a
security problem, but if the server was stopped for long enough, with
some invites to send out email for in the queue, then after starting it
up again, the queue worker would send out emails for invites that
had already expired.

Mateusz Mandera 2ac6a8f829 auth: Change the "continue in browser" link in desktop flow end page.
Fixes #14828.
Giving the /subdomain/<token>/ url there could feel buggy if the user
ended up using the token in the desktop app, and then tried clicking the
"continue in browser" link - which had the same token that would now be
expired. It's sufficient to simply link to /login/ instead.

Anders Kaseorg 365fe0b3d5 python: Sort imports with isort.
Fixes #2665.

Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.

Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start.  I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

Dinesh 0c45e0118f tests: Clear remove/remock approach for ACCESS_TOKEN_URL endpoint.
ACCESS_TOKEN_URL works a different for apple authentication, so,
we removed and remocked the ACCESS_TOKEN_URL mock in
`register_extra_endpoints` override of apple auth test class.
It is cleaner to have it as generic feature of `social_auth_test`.

So, this commit adds a function that returns token_data_dict that
we had earlier and is called in the ACCESS_TOKEN_URL mock.
This function is overriden in apple auth test class to generate
payload of the format that apple auth expects.

Thanks to Mateusz Mandera for the simple idea.

This implementation overrides some of PSA's internal backend
functions to handle `state` value with redis as the standard
way doesn't work because of apple sending required details
in the form of POST request.

Includes a mixin test class that'll be useful for testing
Native auth flow.

other important work on this.

Dinesh d30f11888a logging: Set up a different logger for each backend.
Adds a top-level logger in `settings.LOGGING` `zulip.auth`
with the default handlers `DEFAULT_ZULIP_HANDLERS` and
an extra hanlder that writes to `/var/log/zulip/auth.log`.

Each auth backend uses it's own logger, `self.logger` which
is in form 'zulip.auth.<backend name>'.

This way it's clear which auth backend generated the log
and is easier to look for all authentication logs in one file.

Besides the above mentioned changes, `name` attribute is added to
`ZulipAuthMixin` so that these logging kind of calls wouldn't raise
any issues when logging is tried in a class without `name` attribute.

Also in the tests we use a new way to check if logger calls are made
i.e. we use `assertLogs` to test if something is logged.

Thanks to Mateusz Mandera for the idea of having a seperate logger
for auth backends and suggestion of using `assertLogs`.
