Mateusz Mandera 27c4e46b30 do_deactivate_realm: Add deactivation_reason kwarg.
It's going to be helpful in the future to record the reason for realm
deactivation.
- For information tracking
- For making a distinction between cases where we can allow realm owners
  to reactivate their realm via a self-serve flow (e.g.
  "owner_request") vs where we can't (ToS abuse).

Sahil Batra 7b42c802b1 invites: Add include_realm_default_subscriptions parameter.
This commit adds include_realm_default_subscriptions parameter
to the invite endpoints and the corresponding field in
PreregistrationUser and MultiuseInvite objects. This field will
be used to subscribe the new users to the default streams at the
time of account creation and not to the streams that were default
when sending the invite.

Vector73 ac4dde24ae realm: Add an alias `realm_url` and deprecate `realm_uri` in the API.
The naming `uri` is deprecated while `url` should be used in order to
satisfy URL standards. For this reason, four endpoints are affected:

* The response content of three endpoints `/server_settings`,
`/register` and `/realm` that contain a field `realm_uri` is
changed to `realm_url`.

* In one of the common fields for all mobile push notifications payloads,
`realm_url` field is now added as an alias to `realm_uri`.

For backwards compatibility, we keep the field `realm_uri` and add
an alias `realm_url`.

Vector73 8ab526a25a models: Replace realm.uri with realm.url.
In #23380, we are changing all occurrences of uri with url in order to
follow the latest URL standard. Previous PRs #25038 and #25045 has
replaced the occurences of uri that has no direct relation with realm.

This commit changes just the model property, which has no API
compatibility concerns.

Alex Vandiver d863aa56de invites: Lock the realm when determining invitation counts.
This prevents users from hammering the invitation endpoint, causing
races, and inviting more users than they should otherwise be allowed
to.

Doing this requires that we not raise InvitationError when we have
partially succeeded; that behaviour is left to the one callsite of
do_invite_users.

Mateusz Mandera da9e4e6e54 backends: Implementation of restricting certain backends by plan.
Only affects zulipchat, by being based on the BILLING_ENABLED setting.

The restricted backends in this commit are
- AzureAD - restricted to Standard plan
- SAML - restricted to Plus plan, although it was already practically
  restricted due to requiring server-side configuration to be done by us

This restriction is placed upon **enabling** a backend - so
organizations that already have a backend enabled, will continue to be
able to use it. This allows us to make exceptions and enable a backend
for an org manually via the shell, and to grandfather organizations into
keeping the backend they have been relying on.

Mateusz Mandera 6dd6fc045f realm_settings: Improve authentication_methods param validation.
The endpoint was lacking validation that the authentication_methods dict
submitted by the user made sense. So e.g. it allowed submitting a
nonsense key like NoSuchBackend or modifying the realm's configured
authentication methods for a backend that's not enabled on the server,
which should not be allowed.

Both were ultimately harmless, because:
1. Submitting NoSuchBackend would luckily just trigger a KeyError inside
   the transaction.atomic() block in do_set_realm_authentication_methods
   so it would actually roll back the database changes it was trying to
   make. So this couldn't actually create some weird
   RealmAuthenticationMethod entries.
2. Silently enabling or disabling e.g. GitHub for a realm when GitHub
   isn't enabled on the server doesn't really change anything. And this
   action is only available to the realm's admins to begin with, so
   there's no attack vector here.

test_supported_backends_only_updated wasn't actually testing anything,
because the state it was asserting:
```
        self.assertFalse(github_auth_enabled(realm))
        self.assertTrue(dev_auth_enabled(realm))
        self.assertFalse(password_auth_enabled(realm))
```

matched the desired state submitted to the API...
```
        result = self.client_patch(
            "/json/realm",
            {
                "authentication_methods": orjson.dumps(
                    {"Email": False, "Dev": True, "GitHub": False}
                ).decode()
            },
        )
```

so we just replace it with a new test that tests the param validation.

Mateusz Mandera d3b4cbd182 auth: Add hardening authenticate(use_dummy_backend=True) in do_login.
As explained in the comment, this is to prevent bugs where some strange
combination of codepaths could end up calling do_login without basic
validation of e.g. the subdomain. The usefulness of this will be
extended with the upcoming commit to add the ability to configure custom
code to wrap authenticate() calls in. This will help ensure that some
codepaths don't slip by the mechanism, ending up logging in a user
without the chance for the custom wrapper to run its code.

Mateusz Mandera 56ca307bc1 tests: Delete test_social_auth_backends.
This test is ancient and patches so much that it's almost unreadable,
while being redundant considering we have comprehensive tests via the
SocialAuthBase subclasses. The one missing case was the one with the
backend we disabled. We replace that with a proper
test_social_auth_backend_disabled test in SocialAuthBase.

Mateusz Mandera 1800b2c797 ldap: Tweak AUTH_LDAP_ADVANCED_REALM_ACCESS_CONTROL behavior.
The original behavior of this setting was to disable LDAP
authentication for any realms not configured to use it. This was an
arbitrary choice, and its only value was to potentially help catch
typos for users who are lazy about testing their configuration.

Since it makes it a very inconvenient to potentially host multiple
organizations with different LDAP configurations, remove that
behavior.

Tim Abbott c6fe799369 i18n: Fix default language for users created via API/LDAP.
This fixes a regression introduced in
9954db4b59, where the realm's default
language would be ignored for users created via API/LDAP/SAML,
resulting in all such users having English as their default language.

The API/LDAP/SAML account creation code paths don't have a request,
and thus cannot pull default language from the user's browser.

We have the `realm.default_language` field intended for this use case,
but it was not being passed through the system.

Rather than pass `realm.default_language` through from each caller, we
make the low-level user creation code set this field, as that seems
more robust to the creation of future callers.

Mateusz Mandera a095c34503 saml: Add OneLogin_Saml2_ValidationError to caught parsing exceptions.
This is an exception that we should be generally catching like the
others, which will give our standard /login/ redirect and proper logging
- as opposed to a 500 if we don't catch.

Addresses directly a bug we occurred in the wild, where a SAMLResponse
was submitted without issuers specified in a valid way, causing this
exception. The added test tests this specific type of scenario.

Alex Vandiver 0dbe111ab3 test_helpers: Switch add/remove_ratelimit to a contextmanager.
Failing to remove all of the rules which were added causes action at a

request was added within a rate-limit-enabled block.

Mateusz Mandera 04f5358a76 tests: Flush session in verify_desktop_flow_end_page in social auth.
As the relevant comment elaborates - what happens next in the test in
simulating the step that happens in the desktop app. Thus a new session
needs to be used. Otherwise, the old session created normally in the
browser pollutes the state and can give falsely passing tests.

This should be happening for all social auth tests using this, not just
in that one SAML test, thus moving it inside the helper method.

Mateusz Mandera 8fb0fe96c6 saml: Save SessionIndex in session and use when making a LogoutRequest.
This is a useful improvement in general for making correct
LogoutRequests to Idps and a necessary one to make SP-initiated logout
fully work properly in the desktop application. During desktop auth
flow, the user goes through the browser, where they log in through their
IdP. This gives them a logged in  browser session at the IdP. However,
SAML SP-initiated logout is fully conducted within the desktop
application. This means that proper information needs to be given to the
the IdP in the LogoutRequest to let it associate the LogoutRequest with
that logged in session that was established in the browser. SessionIndex
is exactly the tool for that in the SAML spec.

Mateusz Mandera 3f55c10685 saml: Rework SP-initiated logout config to support IdP-level config.
This gives more flexibility on a server with multiple organizations and
SAML IdPs. Such a server can have some organizations handled by IdPs
with SLO set up, and some without it set up. In such a scenario, having
a generic True/False server-wide setting is insufficient and instead
being able to specify the IdPs/orgs for SLO is needed.

Mateusz Mandera 0bb0220ebb saml: Implement SP-initiated Logout.
Closes #20084

This is the flow that this implements:
1. A logged-in user clicks "Logout".
2. If they didn't auth via SAML, just do normal logout. Otherwise:
3. Form a LogoutRequest and redirect the user to
https://idp.example.com/slo-endpoint?SAMLRequest=<LogoutRequest here>
4. The IdP validates the LogoutRequest, terminates its own user session
and redirects the user to
https://thezuliporg.example.com/complete/saml/?SAMLRequest=<LogoutResponse>
with the appropriate LogoutResponse. In case of failure, the
LogoutResponse is expected to express that.
5. Zulip validates the LogoutResponse and if the response is a success
response, it executes the regular Zulip logout and the full flow is
finished.

Prakhar Pratyush c8a9c0ee04 realm_redirect: Redirect always to the login page with the next parameter.
Previously, entering an organization via 'accounts/go' with the
web-public stream enabled took the user to the web-public view
even if the user was not logged in.

Now, a user is always redirected to the 'login_page' with
the next parameter, if present.

The 'login_page' view is updated to redirect an authenticated
user based on the 'next' parameter instead of always redirecting
to 'realm.uri'.

Mateusz Mandera ffa3aa8487 auth: Rewrite data model for tracking enabled auth backends.
So far, we've used the BitField .authentication_methods on Realm
for tracking which backends are enabled for an organization. This
however made it a pain to add new backends (requiring altering the
column and a migration - particularly troublesome if someone wanted to
create their own custom auth backend for their server).

Instead this will be tracked through the existence of the appropriate
rows in the RealmAuthenticationMethods table.
