Mateusz Mandera cacff28578 types: Fix declared type of custom profile field values.
None of the existing custom profile field types have the value as an
integer like declared in many places - nor is it a string like currently
decalred in types.py. The correct type is Union[str, List[int]]. Rather
than tracking this in so many places throughout the codebase, we add a
new ProfileDataElementValue type and insert it where appropriate.

Mateusz Mandera c4edda016f models: Remove property decorator from UserProfile.profile_data.
Having this as a property is misleading, given that it does db queries

Mateusz Mandera 8ad7520180 ldap: Support alternative attrs to userAccountControl.
Fixes #17456.

The main tricky part has to do with what values the attribute should
have. LDAP defines a Boolean as
Boolean = "TRUE" / "FALSE"
so ideally we'd always see exactly those values. However,
although the issue is now marked as resolved, the discussion in
https://pagure.io/freeipa/issue/1259 shows how this may not always be
respected - meaning it makes sense for us to be more liberal in
interpreting these values.

Mateusz Mandera c460351898 auth: Add logging of successful attempts to social codepath.
The previous commit introduced logging of attempts for username+password
backends. For completeness, we should log, in the same format,
successful attempts via social auth backends.

Mateusz Mandera a4e77d514b auth: Log details of authentication attempts.
These details are useful to log. This only makes sense for some auth
backends, namely email and ldap backends, because other backends are
"external" in the sense that they happen at some external provider's
server (Google, SAML IdP etc.) so the failure also happens there and we
don't get useful information about what happened.

PIG208 53888e5a26 request: Refactor ZulipRequestNotes to RequestNotes.
This utilizes the generic `BaseNotes` we added for multipurpose
patching. With this migration as an example, we can further support
more types of notes to replace the monkey-patching approach we have used
throughout the codebase for type safety.

Mateusz Mandera 78297efefd ldap: Use a workaround instead of forking django-auth-ldap.
Till now, we've been forking django-auth-ldap at
https://github.com/zulip/django-auth-ldap to put the
LDAPReverseEmailSearch feature in it, hoping to get it merged
upstream in https://github.com/django-auth-ldap/django-auth-ldap/pull/150

The efforts to get it merged have stalled for now however and we don't
want to be on the fork forever, so this commit puts the email search
feature as a clumsy workaround inside our codebase and switches to using
the latest upstream release instead of the fork.

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.

Erik Tews 1ecb87ec80 auth: show _OR_ during login only when other methods are available.
There might be good reasons to have other external authentication
methods such as SAML configured, but none of them is available.

This happens, for example, when you have enabled SAML so that Zulip is
able to generate the metadata in XML format, but you haven't
configured an IdP yet. This commit makes sure that the phrase _OR_ is
only shown on the login/account page when there are actually other
authentication methods available. When they are just configured, but
not available yet, the page looks like as if no external
authentication methods are be configured.

We achieve this by deleting any_social_backend_enabled, which was very
similar to page_params.external_authentication_methods, which
correctly has one entry per configured SAML IdP.

PIG208 c03b9c95ad request: Store client information using ZulipRequestNotes.
This concludes the HttpRequest migration to eliminate arbitrary
attributes (except private ones that are belong to django) attached
to the request object during runtime and migrated them to a
separate data structure dedicated for the purpose of adding
information (so called notes) to a HttpRequest.

PIG208 3f9a5e1e17 request: Refactor to record rate limit data using ZulipRequestNotes.
We will no longer use the HttpRequest to store the rate limit data.
Using ZulipRequestNotes, we can access rate_limit and ratelimits_applied
with type hints support. We also save the process of initializing
ratelimits_applied by giving it a default value.

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.

combination with disabling name changes in the organization, can force
users to just use that name without being able to change it.

Mateusz Mandera 4006bb5153 auth: Improve display of errors when user needs to reset password.
Raising jsonableError in the authentication form was non-ideal because
it took the user to an ugly page with the returned json.

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.

Dinesh c5ab01656d auth: Remove Optional for request param of authenticate().
The authenticate function of EmailAuthBackend had request param
type set Optional[HttpRequest] had `None` as default. This
function is never called without a request. So this changes it to
require an HttpRequest parameter.

It was made `Optional` in bc062e1c4d,
because this parameter was new in Django at the time.

We're safe to make it a required argument as everything worked well
before that recent commit and Mateusz Mandera and I checked if it gets
`None` anywhere and found only authenticate of non EmailAuthBackend
gets `None` in some places like `dev_direct_login`.

All the places in tests where this function got `None` as request
were fixed in previous commit.

sahil839 a4c3224328 users: Remove redundant get_role_for_new_user in lib/create_user.py.
The function get_role_for_new_user was added to get role from the
invited_as value, as invited_as values were one of (1,2,3,4)
previously, but it was then changed to be the actual role value,
i.e. one of (100, 200, 400, 600), in 1f8f227444.

So, we can safely remove this function now and use invited_as value
directly and handle realm_creation case by using an if condition.

Strifel 209c89be10 ldap: Add option to limit user access to certain realms.
This adds an option for restricting a ldap user
to only be allowed to login into certain realms.
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 232eb8b7cf auth: Render config error page on configuration error.
We previously used to to redirect to config error page with
a different URL. This commit renders config error in the same
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.
