For get and filter queries of NamedUserGroup, realm_for_sharding
field is used instead of realm field, as directly using
realm_for_sharding field on NamedUserGroup makes the query faster
than using realm present on the base UserGroup table.
(cherry picked from commit 764f4aa2e0)
In 40956ae4c5 we implemented group sync
via SAML during sign in and sign up. The sign up implementation used a
session variable group_memberships_sync_map to plumb through the sync
information to the registration codepath, to execute group sync after
user creation.
We can use a more robust approach instead, and just amend groups on the
`PreregistrationUser` object that's going to be used for registration.
Adds support for syncing group memberships for a user when logging in
via SAML. The list of group memberships is passed by the IdP in the
zulip_groups SAML attribute in the SAMLResponse.
In user signup context, we are okay with there being an existing mirror
dummy user with the matching email - at the end of the signup, that
mirror dummy account will be activated and control of it given to the
user doing this signup.
However, in email change contexts (SCIM API and regular email change
flow), we can't change an account's email address to the address that
already belongs to an existing mirror dummy user.
To avoid subtle bugs like this, we make callers have to explicitly
specify whether existance of mirror dummies with the matching email
address is okay or not.
When a user was joining via a multi-use invitation link, using one of
the social auth methods (e.g. Login with Google), the intended group
memberships configured on the multi-use invite would be ignored.
This extracts the core general group-syncing logic, which is independent
of any LDAP-specific concerns, to a separate function. This allows the
use of this core logic for group sync in other authentication backends.
The code also gets a bit cleaned up in the process to make it more
readable (with some readability tweaks to the log strings as well).
This was broken, due the mechanism simply using our
is_guest/is_realm_admin/etc. role setters, but failing to adjust system
group memberships - resulting in corrupted database state.
We need to ensure that change_user_role is called for setting user role.
There are two relevant codepaths that run the sync based on
AUTH_LDAP_USER_FLAGS_BY_GROUP and thus need to get this right:
1. manage.py sync_ldap_user_data
2. Just-in-time user creation when a user without a Zulip account logs
in for the first using their ldap credentials. After
get_or_build_user returns, django-auth-ldap sees that the user
account has just been created, and proceeds to run ._populate_user().
Now that both user.save() and do_change_user_realm will be getting
called together, we need to ensure this always happens atomically.
This imposes the need to override _get_or_create_user to put it in a
transaction. The troublesome consequence is that this new
`atomic(savepoint=False)` causes the usual type of issue, where tests
testing error get their transaction rolled back and cannot continue
executing.
To get around that, we add a test helper
`artificial_transaction_savepoint` which allows these tests to wrap
their problematic blocks in an artificial transaction which provides a
savepoint, thus preventing the full test transaction rollback derailing
the rest of the test.
This commit updates is_user_in_group and is_any_user_in_group
to accept group ID as parameter instead of UserGroup object.
This is a prep commit for updating code to not prefetch
direct message permissions group.
This implied by its name that users could have more than one key.
They cannot, currently; make the code clearer by switching to the
explicit column access.
The bug we're fixing here leaks information by returning an "invalid
subdomain" error when an attempt is made to log in to user@example.com
on a subdomain X when user@example.com does not exist on X, but does
on another subdomain Y.
This allows an attacker to determine that a certain email address has an
account on the server.
Instead, this should just return a regular authentication error.
We create an unnamed user group with just the group creator as it's
member when trying to set the default. The pattern I've followed across
most of the acting_user additions is to just put the user declared
somewhere before the check_add_user_group and see if the test passes.
If it does not, then I'll look at what kind of user it needs to be set
to `acting_user`.
There was a bug here that would trigger an exception inside
`sync_user_profile_custom_fields`, causing it to get logged with
logging.warning, when an attribute configured for SAML custom profile
field sync was missing from a SAMLResponse or had an empty value.
`sync_user_profile_custom_fields` expects valid values, and None is not
valid.
We could consider a slightly different behavior here instead - when an
attribute is sent with no value in the SAMLResponse, that means the attr
has no value in the IdP's user directory - so perhaps a better behavior
would be to also remove the custom profile field value in Zulip. However
there are two issues with that:
1. It's not necessarily the best behavior, because an organization might
want the "user doesn't have this attribute set at the IdP level" state
to just mean that the user should be free to set the value manually in
Zulip if they wish. And having that value get reset on every login would
then be an issue. The implementation in this commit is consistent with
this philosophy.
2. There's some implementation difficulty - upstream
`self.get_attr(...)`, which we use for reading the attr value from the
SAMLResponse, doesn't distinguish between an attribute being sent with
no value and the attribute not being sent at all - in both cases it
returns None. So we'd need some extra work here with parsing the
SAMLResponse properly, to be able to know when the custom profile field
should get cleared.
Replace the SOCIAL_AUTH_SYNC_CUSTOM_ATTRS_DICT with
SOCIAL_AUTH_SYNC_ATTRS_DICT, designed to support also regular user attrs
like role or full name (in the future).
Custom attributes can stay configured as they were and will get merged
into SOCIAL_AUTH_SYNC_ATTRS_DICT in computed_settings, or can be
specified in SOCIAL_AUTH_SYNC_ATTRS_DICT directly with "custom__"
prefix.
The role sync is plumbed through to user creation, so users can
immediately be created with their intended role as provided by the IdP
when they're creating their account, even when doing this flow without
an invitiation.
This bug was introduced in da9e4e6e54.
validate validate_plan_for_authentication_methods is already called
inside validate_authentication_methods_dict_from_api, conditionally on
settings.BILLING_ENABLED. This additional, redundant call runs
regardless of BILLING_ENABLED, and thus prevents a self-hosted server
from enabling certain backends in the organization settings UI.
The impact of this is limited - in order to encounter this bug, a
self-hosted server would have to first disable the backend in the UI, as
self-hosted realms are created with all backend flags enabled. A backend
doesn't show up in the org settings UI until it is first enabled in
AUTHENTICATION_BACKENDS in settings.py - that's why this is a rare
state. A sequence of steps like this has to be followed to reproduce:
1. Add the backend to AUTHENTICATION_BACKENDS in settings.py.
2. Disable the backend in the org settings UI.
3. Now try to re-enable it, which fails due to the bug.
SHA1PasswordHasher will be removed in Django 5.1. MD5PasswordHasher
will remain for the purpose of speeding up tests.

Creates a new "realm_deactivated" email that can be sent to realm
owners as part of `do_deactivate_realm`, via a boolean flag,
`email_owners`.
This flag is set to `False` when `do_deactivate_realm` is used for
realm exports or changing a realm's subdomain, so that the active
organization owners are not emailed in those cases.
This flag is optional for the `deactivate_realm` management command,
but as there is no active user passed in that case, then the email
is sent without referencing who deactivated the realm.
It is passed as `True` for the support analytics view, but the email
that is generated does not include information about the support
admin user who completed the request for organization deactivation.
When an active organization owner deactivates the organization, then
the flag is `True` and an email is sent to them as well as any other
active organization owners, with a slight variation in the email text
for those two cases.
Adds specific tests for when `email_owners` is passed as `True`. All
existing tests for other functionality of `do_deactivate_user` pass
the flag as `False`.
Adds `localize` from django.util.formats as a jinja env filter so
that the dates in these emails are internationlized for the owner's
default language setting in the "realm_deactivated" email templates.
Fixes#24685.
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).
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.
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`.

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.
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.

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.
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.
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.
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.
